Extuder Idler Hanger

[Edit: 22-02-2019
The bearings are 685 ZZ or RS or whatever. Just 5mm ID and 11mm OD.

BONDTECH
I have tested some china clone Bondtech gears, which came with a 15$ kit. needless to say the kit had bad plastic molds. Even without a stepper motor it was very rough to turn even 1 gear, let alone aligning and turning the second gear.

The bondtech gears are nice. Just throw away everything into the box that came with the kit, and only keep the gears. Needle bearings are a choice, but can be thrown away as wel, since I use a 5MM shaft, and it kinda works the same. It just needs to spin freely really and we have 685 bearing for that. It needs a different version, I'll add it later after I've tested it.....

I still haven't tested any of these, I just played with some filament and pushed it through]

I HAVE NOT YET TESTED THIS
But it looks cool though.

Some weird kind of idler I came up with and spend quite some time altering. there is also a different version, but I omitted i
