The wise Tunk the trunk had outlast many of his forest friends over the course of a couple of hundred years. It sure has seen better days yet it remains standing strong while the rest of the forest is no more. All his tree friends have been chooped down and remodeled to serve humans as furniture or toilet paper.
The trunk is hollowed with the top open so you can also use it as a container for example for pencils or use it as a vase or even plant something in it. There is also a optional cap you can print. Furthermore there is a version in which the bottom is also open, this version is intended for resin printing so the resin can easily run out through it. What you see in the pictures is printed in resin in the default size.
No support is required for printing. If you print in ABS or PLA I recommend printing it at 150% or higher at 0.1 layer height to get the most details out of it.
