This is my fidget spinner full printable with very low friction!
The mechanism is a compromise between minimum contact surfaces and center shaft resistance.
The 2 most important printing parameters are:
- 90/95% to maintain high weight.
- 5 line of perimeters to prevent holes in the center shaft.
The material used is PLA easyfill by Formfutura, https://www.waxplast.com/store/p97/EasyFil%E2%84%A2__-_PLA.html
The assembly is simple,
Smooths moving surfaces
Lock the disc to the shaft with a drop of glue
I did not make a joint To avoid fragile parts.
