Handle for 3mm Allen key

Handle for 3mm Allen key.
It is very useful when assembling prusa i3 MK3.

The 3mm Allen key fits perfectly into the handle.

Maybe you need a oil when put allen key into the printed handle part.
I recommend a zip tie in the Prusa i3 MK3 kit, but it's okay if you have a proper zip tie.

Using a 1.75mm filament, apply oil to the inside of the hole
and assemble the allen key.

If you don't use oil, you'll have a hard time assembling it.
