Description
This is a redesigned version of the Antigravity Arm Floats. The original version and background info can be found here: https://hackaday.io/project/14809-antigravity-arm-floats.
This design is stronger, lighter, easier to print, and is adjustable. The set of files contains every plastic piece I used to create Arm Floats for my daughter, who is now ~70 lbs (32 Kg) and mounts to her Zippie wheelchair.
Other parts I used:
M4-40 screws (7)
M4-35 screws (4)
M4-30 screws (2)
M4-25 screws (1)
M4 lock nut (9)
M8 nut (1)
M8 fender washer (2)
M8 Knob (I used 50mm long, but 40mm or even 30mm would probably work fine)
Silicone Rubber Bands (usually used for cooking, these last longer than regular rubber bands)
MF84ZZ bearing (26)
MR84ZZ bearing (16)
print with 100% or near 100% infill
