Improved Fidget Spinner - designed for PLA

thingiverse

Improved Fidget Spinner Gadget PLA suffers from poor wear and creep capabilities. I started with a basic Fidget spinner design but by day's end, the center bearing had become loose. This model boasts a split collar that improves upon capturing the center bearing and allows epoxy or other glues to bond plastic to plastic without damaging the bearings. At this posting time, I've used it for only a few days and it remains firmly assembled; however, its long-term durability is still uncertain. Things you will need: Epoxy or Gel Glue 4 x 608 bearings (skateboard bearings) This design also functions with one bearing at the center but performs better with four Foam tape, electrical tape, or other types of tape for finger pads Assembly is straightforward. 1) Begin by working on the center. Test fit this part first. Place one collar onto the bearing. Apply a small amount of epoxy or similar gel-type glue where the plastic ends meet the bearing. Insert the assembly into the center (the fit should be snug). Now insert the other half of the collar into the opposite side. 2) Using pliers to press the bearings into the outside openings, you can partially insert them before using a vice to press the bearings straight into the spinner or work from side to side with pliers to press them in straight. 3) Insert one pad into the center bearing. Add a small amount of epoxy or other gel glue into the center of the bearing and install the other pad. 4) After the glue has set, add foam tape or electrical tape to the pads to provide extra grip when spinning. For my printer settings and the attached file, the bearings need to be pressed into the PLA using pliers and/or a vice.
