About this 3D model

I recently started getting into pen turning and needed a mold to make my own blanks. I initially intended to make a typical silicone mold but screwed that up. Being impatient, I decided to see if a TPU mold would work. Good news, it does! So far I've pulled 4 blanks out of the same mold and have another one curing right now!
