File Handle

After using metal files for years with just their tangs for handles, I decided it was time to create & print a set with my new Prusa i3 MK3.

Naturally, I chose to use wood filament for the prints...

:-)

A few alternative uses:

You can always colour-code your toolset with different coloured handles - or even use it as a cord-pull for a window blind or bathroom lightswitch!

You can also improvise and use it as a make-shift allen/ hex-key handle, by placing the short end of the hex-key into the hole (for the hand file's tang in the front end of handle) and hold it there with your thumb, to get a finer adjustment or a little more leverage...
(See https://www.thingiverse.com/thing:3604772 for a better solution than the above method!)

Depending on the rod's thickness, even as a dowsing-rod handle!
