Mosaic Palette Filament Roller Guide (any angle)

thingiverse

###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](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 1. Insert the 608 into the ring 2. Insert the "Asse" into the 608 3. Take 2 "Bearing Holder" and use the M3 to fix the assembled 608+Ring through the hole 4. 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](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.
