This is a modified SB Mini dock that I added longer supports for the Anthead toolhead. This dock work for liftbar, Stealth Changer and Tap Changer projects.

Magnet insert points have been added to help keep the toolhead locked in the dock when not used. This is an easy and non-mechanical approach that has a low failure chance.

I recommend ASA or ABS to print this dock. 15% to 20% infill is good. It is not a high stress part. Supports are optional. Tree supports will work best for most printers but this can be printed without supports if you print it slow enough.
