V0.7

A little big this time, but much better for contact (probably less friction)

V1

Back to the v0.2, but closed on the sides to make some tests : it have some friction but it works :)

It feel smooth (maybe more than the PLA Bushings I used sometimes), and often fall under it's own weight of only 6gr (with 9 balls, three in each line)

(don't know how it will endure times though)

(For the next time : in fact the balls are more sliding than rolling... and 4 balls was better, plus a 2 shells perimeter)

V0.6

all I need to do now is to find the right size to compensate the contraction of the plastic (hmm, maybe with another shape, closing the loop seems to be the hardest part)

V0.5

/!\ The tube are not flat but a little curved along the diameter

V0.4

V0.3

I finally found how to model that !

V0.2

It works :)

Hmm I need to find how I can close the loop of balls now...

V0.1
