Fidget spinner addons

Some fidget spinner addons I slapped together over the weekend, partly because I don't know when I'll get to a bearing shop.

1. bearing_nut_adaptor - adapt a m8, m10 or 3/8" nut to fit in your favourite fidget spinner (replacing the bearings used as weights
2. pla_bearing - a pla fitting that fits inside the centre hole of your favourite fidget spinner as surprisingly good bearing replacement (i.e. works comparable to normal bearings, but doesn't come close to low resistance bearings)
3. bearing_press - tools that make it easier to press in bearings into your favourite fidget spinner.
