Superslim 0.35mm nozzle spinner

This is purely experimental spinner.
I considered to put a fillet or chamfer on the edge but the walls are only 0.7mm thin so there is no room to print it correctly.

Print with a 0.35 nozzle and with "single wall" setting. There is no space for more walls.

The holes are diameter 22.3mm and gives good friction to the skate/inline ballbearings when printed on my printer.
