Just a real simple quick design. I made a cap cover for the SC31 Pro flashlight. 

I printed in TPU. I had to do +/- 0.5 to 1 percent on scaling in the slicer to dial it in, then imported those changes to the file. I've included both STEP and STL in case you want to edit it  for whatever reason. It has a small engraving of SC31-P on the bottom. 

No supports needed of course. This file printed for me great.
