IMPROVED- I found my clip slipping out of the holster and figured out that the round part was too small and would fall out of the retainer. 

I have increasded the size of it and haven't had it come out once.

This is a replacement for the AlienGear Standard Toolless Holster Clip.

This does contain non-manifold edges that I do not know how to fix, but Bambu Studio repairs them perfectly. I do not know if other slicers do or not. I will include the .blend file if someone else can/needs to fix it.

Print it on its side with supports for easiest print.

I did 75% gyroid infill but you can do whatever you want with the infill. For some reason I have had defects in the half moon part with 100%. Strength may vary though.
