Handle for 3mm Allen key
thingiverse
Handle for 3mm Allen key. It's incredibly useful when building a Prusa i3 MK3. The 3mm Allen key slips perfectly into the handle. You might need to add some lubricant when inserting the Allen key into the printed handle part. I strongly suggest using a zip tie included in the Prusa i3 MK3 kit, but a proper zip tie will also do. When working with 1.75mm filament, apply lubricant to the inside of the hole and then assemble the Allen key. If you don't use lubricant, you'll find assembling it extremely difficult.
