The belt clip of one of my Motorola 2 way radio broke, so decided to design it from scratch. It is the part that goes inside the main body of belt clip. I have designed it in such a way that if it ever gets broken again, can be easily printed and replaced.
I have also attached another stl file with built-in supports. Please print it in that way/orientation only for maximum strength.
Also have attached the original stl file with no supports. If you download/collect, do like it too :-)
Carefully remove all supports and file the part if necessary, to make it smoother. Install the original spring and slip it inside the main clip body until it clicks. Enjoy :-)
