Anyone have a link to the fleshlight stl?

To print the shell, maybe ? To print the nice part, terrible idea !

Even with this new perfect tpu??!
Should I cancel my order? Shipping from CR isn't cheap.

TPU is a little too rigid for that kind of use, it would not be comfortable.

You'd ideally want to print a mold and then use silicone to fill it in and use the silicone as what you "interface" with.

But you definitely could use tpu for the shell that holds the silicone interior.

Using 3D prints as sextoys with any kind of materials is a bad idea because of higene. The layer lines will accumulate lots of dirty stuff and are basically impossible to clean. Same goes for food related items.

Ive seen people use beeswax as a mold release, it apparently works really well as a release and fills in the layer lines in the mold so that don't transfer to the cast. Or at least that what I've read.
