Leatherman Arc Saw/File Thumb Stud

I wanted to be able to open the file and saw on my Leatherman Arc with my thumb so printed a simple insert. It would probably be more comfortable to print out of TPU (scale up 1-2% if you do for a snug fit) but I printed it normal scale out of Onyx, 0.2mm layer height. 

Edit: The saw hole seems to be slightly wider than the file as it fell out after a week.  I'm going to try scaling it's width slightly to make it a snug fit like the file.
