Kossel 2020 flex printed roller

In my quest of building a Maxi kossel with 2020 extrusion,

i've tested these http://www.thingiverse.com/thing:566093 with POW shower roller. i found that the carrier wobbling a little bit.

i've try with 608 bearing, but metal on metal is too noisy for me.

So instead of paid 80€ for proper delrin rollers.

I've try to made my own with a bunch of MR83-ZZ bearings.

theses rollers can be printed in pla or flex.

PLA works but i try to make the kossel as quiet as possible.

(ecco)Flex roller a smoother and make no noise but even at 100% infill it have a tendecy to bend and make delta printer inacurate.

ps: Print settings

E3D 0.4 nozzle,

0.15 layer height,

4 perimeters,

100% infill

speed 60mm/s.
