This is simple file handle suitable for small needle files with 3.5mm handles.

The handle is 50mm long and 11mm diameter.

I made this because most of the ones on Thingiverse were too big for my liking.

If the hole is too small when printed, just use a cordless drill running in reverse with a 3-3.5mm drill as required. Don't run the drill forwards as this will cause it to 'grab' and you'll probably end up with a misaligned hole or injury.

Print this on a raft or brim with 3 perimeters and 25-35% infill
