Linear Bearing (16mm tube)

This linear bearing consists of 5 races, which are printed separately. Each race contains 18 (copper) balls of 3.2 mm. I got the balls from the Dutch "Huis en Comfort" site: http://www.huis-en-comfort.nl/Glasreiniger-kogeltjes-480899.html?group=765764.

If you want to use a bit larger diameter tube, you only have to design the outer housing yourself (the pentagon-like thing) and make it a bit larger. The races will fit in the corners and give a nice smooth run.

Have Fun!
