So the clip that came with my FitBit One started to break down and eventually ripped apart from me putting it on my pants/belt/pocket. I've been holding the FB One in my pocket but it isn't very secure that way. I was looking on Thingiverse for a solution but all I could find was the watch band ones.

Here is a mash-up of a couple items I had lying around in my bag of tricks and somethings I found on here.

A little bulky but it does the trick. Now I can clip it on my pants again!

Had to make this in two pieces for easy printing without supports.
