Nimble Gimbal For 2020 Delta Frame

thingiverse

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 x 5mm bearing size of the 624's. 4. Also used four bearings instead of the two in the original design. (A little over kill) Needed supplies: Print one set of arms and one extruder_mount_bracket. 6 M4 x 16mm bolts, 4 for the arms to bolt to the 2020 beam and 2 for the bearings. 4 M4 x 20mm bolts for mounting the Zesty Extruder Motor mount to the gimbal bracket. 18 M4 flat washers (8 for the 4 bolts to mount the Zesty Motor mount to the gimbal bracket (optional), 4 for the M4 bolts that mount the arms to the 2020 beam (optional) and 6 for the M4 bolts that make up the two bearing assemblies). 6 M4 nylon lock nuts, 4 for the Zesty motor mount to gimbal bracket and 2 for the arms to gimbal bracket. 4 M4 'T' nuts for the M4 bolts the attach the arms to the 2020 beam. 4 624 size bearings. Assembly Instructions: Assemble the bearings first by using 1 M4 x 16mm bolt, 3 M4 washers and 1 nylon lock nut. Slide 1 M4 washer onto the bolt followed by a 624 bearing, then another M4 washer followed by a 2nd 624 bearing. Then slide the third M4 washer and lastly the nylon lock nut. Now tighten the bearing assembly. Make one more assembly. Take 1 bearing assembly and insert it into the bearing housing on the motor bracket button head first. Do the same for the other bearing assembly. Please see the provided photos for assembly.
