About this 3D model

This is a simple billiards chalk holder (just the base) that grips the chalk sides tightly if printed at an accurate size (22.7mm from inner wall to inner wall on my chalk). Printable in PLA but a Hard TPU or PETG, etc with a bit more compliance will be better. (this is the very first thing I designed and the very first thing I ever printed apart from bed level squares!)
