stg44 bakelite grips

I have a Shoei stg44 that I'm rebuilding. The wood grips are missing. The set of reproduction ones I have don't quite fit. Since I'm going for a late war with mixed finish look I though bakelite grips would look good.

Started with a drawing of the wood grips. Took some dimensions from a mp40 grip for the ridges. Did a little bit of guessing. Compared it to some pictures. Might not be exact, but it looks pretty close.

The locating pin holes should be 6.5mm. That didn't fit my grip frame. Had to open them up to 7.5mm. That's the size I left the stl. The Fusion 360 file is included, so it can be changed if needed.
