3D model description

Mount based on Aurora Tech's mount, but made to be 55mm and also to use the aluminum front clamp for more rigidity.

Print with many walls and many top and bottom layers. I did 11 walls and 15 top/bottom and 60% infill. Don't use PLA as it will be soft at higher temp.

Need two pan-head wood screws - #4 by 1 inch long.

Need four M6x1.0mm pitch nuts.

Need to drill the two holes in the brass nut flange to allow the wood screws to pass.

Trash the weak spring that comes with the brass nuts and replace with a stronger compression spring, 3/4x1/2 with 0.054 wire. I cut down a 1-3/4 long version from Ace Hardware. If you don't do this, not only will you have more potential backlash, but the top nut will probably just spin freely since I didn't design it to lock into the bottom nut.

This should work for any 55mm motor. I chose a 600 watt brushless, but if you are ok with less power, there are cheaper motors.
