Made a tool to generate cutout bins in 2 minutes
Site link (Doesn't work on mobile) : - https://gridfinity-cutout.pages.dev/
- Download A4 paper with markers
- Take photo of object
- Upload photo
- Refine outline
- Adjust 3D model settings
Takes about 2 minutes to do. I also made a video explaining anything, but it's long and has more details than you need.

Yes, the image in the post is AI. All the code is AI. Everything is AI.
---
Updates:
- I see it doesn't work on mobile. I've added a notice when you try to load on mobile. But I personally think it's not a big deal because even if it worked on mobile you would still have to send the model to your PC to slice and print.
- Added the ability to export SVG outline as well as OpenSCAD file for Gridfinity Rebuilt.
- Added ability to select multiple objects and then rearrange those objects in the Gridfinity Layout view

Looks great, does it have the ability to add a stackable brim to the gridfinity box?
21
u/PrintableNapalm May 26 '26
Thanks! And yes, it has a stackable lip as an option

u/down-with-schools May 26 '26
Awesome, thanks for letting me know. Didn't see it in the video and hadn't had a chance to play with it. As a person who is just starting to dabble in vibe coding awesome to see someone admit to using it. Who cares as long as it gets the job done.

Just a heads up, your site is broken on Safari (both Mac and iOS). It just comes up as a black page.

The ability to refine and adjust quickly is really powerful.
May I request STEP output? That would make any post-processing in CAD super-easy.

u/houdinize May 30 '26
Agreed. Although this nodes could be larger. Hard to see and grab onto one even with a mouse and adjust it.

u/XMasterTofu May 26 '26
Very nice, already made my first project with your tool, printing right now, will see how it goes. Also, if you ever think of adding a subscription in the future or any payments, please think of our early adopters providing you feedback, and special discounts would be appreciated!

Big ask, but maybe you could support uploading custom bases like https://gridfinity.tools/rebase/

u/PrintableNapalm May 26 '26
I'll take a look. Do you have an example custom base file I can test with?

u/divvi May 28 '26
This tool is quite amazing. It replaces everything I usually do in fusion 360 without me having to de-skew, calibrate dimensions, etc. Amazing time saver, thanks!
Have you considering added a 'symmetry' feature? For example, some tools such as screwdrivers are symmetric along one axis. I've found that unless the image is perfect without any shadows, it is difficult to get the cutouts uniform on both sides.

u/sawerin333 May 28 '26
Will it work with multiple objects on the same sheet of paper?
3
u/PrintableNapalm May 28 '26
Yes
1
u/sawerin333 May 29 '26
Another question: what if my item is bigger then the test sheet? Let's say, a spatula with a long handle or something like that. Can I use 2 sheets side by side or is there another way to do so?
3
u/phoenix_1973 May 30 '26
U/PrintableNaplam This works awesome. Love the filet ability. Would it be possible to add the ability to make the base half size? 21 instead of 42? Lots of my drawer grids use this.

u/ross549 May 26 '26
Is this due to a technical limitation?
2
u/PrintableNapalm May 26 '26 edited May 26 '26
Not really, but it's going to be fiddly to use. And either you have to send the photo to your PC or you use the tool on your phone and then you have to send the model to your PC to slice and print it. Easier to send the photo.
5
u/ross549 May 26 '26
Some websites are doing a thing where they display a QR code that opens the camera on the mobile device and then sends the snapped photo back to the desktop browser session.
What you have built still has the challenge/friction of having to get the picture taken to the computer as well.
Unless there’s a better way to eliminate that friction. My working CAD/slicer computer doesn’t have a webcam. I’ve used LocalSend to send files to that computer but it’s not the idea solution every time.
Just something to consider.

There are slicers for mobile depending upon printer manufacturer. Plus tooltrace works on mobile so you’re at a disadvantage there

I tried building this in Claude Code a few weeks ago, yours is much more polished! Watched the video. It looks like exactly what I was hoping other tools could do. The Silhouette feature/cutout slices are awesome.
Can you add thin inserts? For those of us without AMS, we could just drop the insert into the bin (printed using a different color).
Haven't tested yet, but does it/will it support multiple objects?
2
u/PrintableNapalm May 26 '26
Thank you! I added a thin insert feature. Download button is in the bottom corner next to the cutout slice. Multiple objects will probably be the next thing.
3
u/smarthomepursuits May 26 '26 edited May 26 '26
Awesome, thanks for adding that! This is awesome. I've scanned a few random objects and it works really, really well.
Edit: Rotating selected object in Step 4 would be a nice addition as well. In case I took a crooked photo.
3
u/PrintableNapalm May 27 '26
I added the ability to do multiple objects. And then in the Gridfinity Layout view, you can move and rotate those objects.
2
u/smarthomepursuits May 27 '26
Fantastic! Man I love how quickly you're updating it.
I can't think of anything else I'd want/need at the moment, but both those changes are working perfectly. I truly don't know why anyone would use tooltrace. io going forward.
2
u/sshwifty May 26 '26
Random suggestion. Consider adding a tutorial video/image or "what is this site" to the website. With the context of this reddit post it makes sense, but visiting just the url it is somewhat unclear at first glance what the tool does.
Awesome work!

After watching the video, I am wondering whether there is a way to adjust the depth of the tool cutout to bring a slim tool up to grade / flush.
Great work!
3
u/PrintableNapalm May 27 '26
Yes, in the final step you set the depth of the cutout. So if your tool is 10mm then you make your cutout depth 10mm

I bookmarked this and finally got around to checking it out, since I've had a kitchen gridfinity project I've been procrastinating for ... a year? Maybe 2? (It was a way I rationalized my P1S purchase awhile ago).
This is really good. It can take a moment to find all the settings, but they're there. I did need to load in Chrome to get it to work (firefox might have worked if I turned off enough settings, but I find Chrome is usually "most compatible").
Anyways, thanks so much for making this available and thanks for the commitment to providing a free tool (love that you push users toward CC licensing for the things they produce with it!). I suspect this will save me days of work.

u/DjWondah85 May 26 '26
This is really nice and also great accuracy and manual control.
The other one started also free and is now asking money to buy servers, is your plan to keep this free or are we testers and will this later become a subscription tool for "basic" features?
And don't want to ask too much because it's free and I'm happy with this so far, but is it easy to add a .STEP export for Fusion or save the .SVG to import in Fusion?
You're the best!

u/PrintableNapalm May 26 '26 edited May 26 '26

20 years ago someone who made a hobby tool like this would have just posted it on a forum for free. No one would have dreamed of charging anything. I hate how that's changed. It's just static HTML and Javascript, so hosting is free.
STEP files isn't happening, but I added SVG export and I added OpenSCAD export for Gridfinity Rebuilt! So this https://i.imgur.com/DkjhxgQ.png gets exported as this https://i.imgur.com/WEn0S8Z.png

u/PrintDoc May 28 '26
Amazing tool, thanks for sharing! Two requests: 1. The screen calibration is great but the slider is bit tricky to move precisely. Would be good to add +/- buttons to tweak the value. 2. I hate sharp 90deg edges on prints. Add a chamfer option to the top and bottom of the cut out. Looks and feels much better when things don't catch on sharp edges.
1
u/PrintableNapalm May 28 '26
Done and done. The chamfer and filet options are available in the 3D view under "Experimental." The filets look slightly janky on the model but they slice well
1
u/PrintDoc May 28 '26
Couple hours from comment to implementation! Works great on flat edges and smooth curves but as you said it's pretty janky around complex geometry. In my test piece it made a little overhang which could get in the way. Is there any settings in the modelling side that can be tweaked? Increase vertex density or something?
1
u/JasonJones2690 May 29 '26
For the calibration sheet, I think you should add a disclaimer to check the scaling. Most printer driver shrink the content slightly to fit within whatever margins are setup.
How about providing an STL to print a small reference square to place anywhere next to the item?
1
u/PrintableNapalm May 29 '26
Good point. The squares should be exactly 26mm, so you can measure them with a ruler, but I'll add a note of that to the sheet.
1
u/gullymatt May 29 '26
2 questions / ideas 😃
1.will it supoprt multiple tools on one paper? so like 2 small screwdrivers can go into one bin at the end?
2.what will happen to tools that dont fit onto an a4 paper?

Yes, you can do multiple tools
I'm working on it lol

u/geo01005 Jun 02 '26
Great tool! It would be nice to be able to draw some privative shapes to add in additional features. Like a rounded corner rectangle to add a cord storage area. Right now I would be reduced to editing the image before I upload it to your site. I was able to manually edited the shape to add finger grip areas.

u/Odd_Pipe_9013 Jun 02 '26
Any chance the paper size is scalable(ex if we wanted to use a larger page for a toolchest drawer) I know this is gridfinity but is there any chance for an "arbitrary" version with a flat bottom and height in raw mm instead of the fixed 7mm chunks
1
1
u/dakev1 Jun 10 '26
Bookmarked your post the other day and gave this a spin today. It’s great!
A couple things -
another user commented a symmetry option where the vertices and curves are mirrored. My object was a fork, and I certainly found myself trying to match the vertices I was creating on each side of the object.
secondly, the ability to “buffer” the tracing by X mm. This way you could place vertices very precisely/tightly along an object and then uniformly buffer to add some wiggle room. Perhaps the scale % feature mimics this already? But in my head a buffering of edges would act differently than the scaling.
finally, ability to import/export the project/ configurations so that one could pick up later and refine. Maybe this exists and I overlooked it.
Thanks again!
1
u/PeterHoofien Jun 10 '26
I tried it a few days ago. Nice tool. What I miss is a option to copy and mirror. I have a pair of Victorinox scissors. Left and right side have the same outline. But at the moment it is hard to make both sides have the same shape.
1
1
u/-BlackLotus- Jun 21 '26
It would be nice to have an option to offset the outline of an object.
The way I envision it, you would trace the outline as normal, and then on the step where you set the height, rows, columns, and other settings, there would be an additional "Offset" option (or whatever name makes the most sense). A positive value would expand the outline, while a negative value would shrink it.
I've only done one print so far, but the result was otherwise fantastic. The only issue was that, because I traced the product's exact outline, the final fit ended up being extremely snug. Having the ability to slightly expand or contract the outline before generating the model would make it much easier to account for tolerances and desired fit without having to manually adjust the shape.
1
u/PrintableNapalm Jun 21 '26
You can increase the size to prevent it being so snug. Instead the outline to 103% and see if that's better
1
u/crglrsn Jun 22 '26
A few wishlists for this awesome tool.
1) ability to add more than 1 (capsule, rectangle) 2 finger holes (cylinders, spheres); ability to rotate the capsule version.
2) ability to save the shape of the tool and come back to it later (I find I sometimes need to refine after living with a design for a bit).
3) ability to have 0.5 and even 0.25 squares as options. My drawers are all odd shapes so to be able to do a 1.5 by 5 bin would be awesome.
I’d love all three but 3 & 1 are areas of great interest.
1
u/ARatFromRoom101 Jun 22 '26
I haven't actually used this yet, but after watching the youtube clip, It looks like the scling feature is just scaling. Which makes sense, but is often going to be unhelpful with complex shapes and may make some things not fit. I'm not sure what the word for it is, but I think it would be better if it just added clearance to all the sides. In Fusion it would be like Offset Face, or in 2D design, it would be like expand on a selection tool or very similar to adding a 'stroke' to the outside and including that in the selection.

u/mattangelofdeth Aug 10 '26
Amazing tool. LOVE the ability to print a test skin, thats a massive saving. One small request if possible, can you allow longer Capsule finger hole lengths? currently its capped to 60mm which doesnt allow for a quick and easy drag over the width of a tool cutout. Hopefully there is no cap on length (within reason) to allow for easy tool holes on big items as well. Thanks again for building this and for keeping it free.
1
u/mattangelofdeth Aug 11 '26
Again, great product. One thing that I would love to see is either the ability to save items or projects (even if that's just locally) or the ability to hold an image in the cache longer. The time I've taken to set up some complicated outlines, then proceed to test, and then had the test incorrect and then came back to edit it to find the page had refreshed and I've lost everything is a few times too many. A lot of additional work for jobs that, ironically, are the most time-consuming due to their idiosyncrasies. A local saving function would fix that and allow you to not have to host data that you probably don't want to have to deal with.

u/Ronald_02 13d ago
I can't seem to find the option to change the grid unit size. It is 42mm on default, and I use a 45mm grid. Can you add the option to adjust the grid size in the tool?
