Peugot Pepper Grinder Bottom Replacement

A low effort replacement for a Peugot Pepper Grinder bottom. I believe this is for a Peugot Paris model but am not sure. 

The bottom wood section of my pepper grinder fell off after getting too hot from being near the stove, so one of the very first things I made with my 3d printer was this replacement bottom, and only just got around to uploading it now. 
 

I made it using TinkerCAD and didn't know you could increase the number of sides, so it's polygonal, and I didn't know how to make threads so it's just scalloped on the inside and designed to be jammed on. This also means that it no longer works for selecting the fineness of the grind, but that can be adjusted by loosening the screw on top.
