Mosaic Palette Filament Roller Guide (any angle) by StarLord81

Roller guide (smoother than bowden)
Roller guide for filament, used to allow passage of filament from the roof of heated chamber.
Originally designed as counterpart of https://www.thingiverse.com/thing:4646566 but you can use also alone to guide the filament through different route.
To assembly you need to print:
8 x Bearing Holder
4 x Asse
1 x Extruder base
4 x External Ring
Also needs:
4 x 608 bearings
4 x M3x20 (screw and nut)
Assembly
Insert the 608 into the ring
Insert the "Asse" into the 608
Take 2 "Bearing Holder" and use the M3 to fix the assembled 608+Ring through the hole
Glue the assembled holder to the base
Repeat more 3 time.
Fix to the wall of the chamber with M3 of your choice.
If you use https://www.thingiverse.com/thing:4646566 as counterpart (if you need one) the holes of both items are parallels.
Update 1
I noted that when the Palette 2 motors does retraction the filament tend to exit from the roller (this doesn't happen during normal use but the retraction of the Palette it's really huge).
I added some guide that can be added to the structure and avoid exit from the bearing ring.
If you want to use them you need to print also:
4x Antislip
4x Antislip-cp
and replace M4x20 with M4x25
Optionally you can use some glue to join the Antislip but isn't really needed.
