Simple tool holder female rail

This tool holder was designed to be simple and compact.  It holds all the required allen wrenches for servicing a Dillon XL650.  It was printed at .16MM layer height with a 20% infill.  I used HATCHBOX Grey PLA filament.  The cup was made to hold screws and parts removed during servicing.  It mounts to any of the male rail mounts and I typically move it to the wall mount when not in use.  I redesigned the allen wrench sizes multiple times to try and get them to fit loose enough for easy removal but allow them to still be hard indexed.  I ended up printing with tighter dimensions and then heating each one up with a heat gun and fitting them in the holder while hot.  This gave me the fit i was looking for.  Prints right side up with no supports.  See it on Thingiverse!
