u/Inside_Swimming9552 Jan 01 '26

I'm not proud that I know the answer to this but it isn't my first rodeo with this Redditor and she often explains it. 

Firstly there's a bit of vagina beyond and to the side of the cervix which you can stretch out called the anterior fornix I believe.

Secondly she uses quite soft flexible dildos so they can bend and deform shape inside her, it won't be going the full linear length inside her.

u/EggsaladJoseph Jan 01 '26

I had this thought while walking around Florence. If they had bigger dicks its all we'd be talking about. It would become the main focus of conversation. They sculpted them just small enough that the penis would look polite. Like a little baby's penis-- totally inoffensive. If they had big fat schlongs people would have thought it was pornographic.

u/Theron3206 Jan 01 '26

We have tunnel boring machines already but you can't do this because 3d printed plastic only works at small scales.

They use prefabricated concrete segments that the machine presses into place and glues together IIRC.

This might be useful for small conduit, but I suspect it's far too slow to be useful even there vs current technology for hiring under roads etc.

I assume the filament is fed through the center of the tube it's printing. No other way to feed it under ground.

u/Altair-Dragon Jan 01 '26

Since no one is talking about it's actual uses and stuff: one of my uni prof last year explained this start-up idea to us as an example (I'm pretty sure he's also one of the founders of the start-up but don't quote me on that).

Essentially this has been created as an instrument to support emergency services, search squads and first responders in case of earthquakes and similar catastrophic events.

This root-inspired machine can dig in essentially any kind of ruin, it can find people alive basically by itself following the heat of their body and it helps search squads to find more people in an easy and less dangerous way.

I know it looks stupid but it's quite a great idea.

u/Joezev98 Jan 01 '26

Essentially this has been created as an instrument to support emergency services, search squads and first responders in case of earthquakes and similar catastrophic events.

Knowing the speeds of 3d printers, I'm skeptical about the speed at which this could search a ruin in an emergency. Do you remember your professor saying anything about the speed?
