Nimble Gimbal For 2020 Delta Frame

I saw slonold's Nimble Gimbal and liked the Idea. slonold did a great job on his design. I needed to modify it for my application.

1. I needed to make the arms wider at the bottom so it would mount on a 2020 aluminum
extrusion beam.
2. I want to use M4 bolts to attach the arms to the 2020 beam so I increased the M3 holes
to M4. (A little over kill)
3. I have a dozen 624 bearings and wanted to utilize them. I increased the size of the
bearing housing to accommodate the 13mm
