Back wheel filament guide for Ender-3 S1 (Pro/Plus)

You need 608 bearing for this model! Buy it, steal it or print it if you dare.

Hub fits in standart S1 arm socket. Made to guide filament from behind of printer.

I recommend 30% infill for all parts

You can print it with any plastic you want with layer height up to 0.3 however for hub part I recommend 0.2 so it fit into socket smoother. Also, for HUB I recommend support “Lines” without interface and overhang angle more than 55 (no supports should be inside)

You will also need a hammer to fit bearing into wheel. Dont worry, it wont break it and will stay there forever and ever.

Bearing fits onto hub easily and stays there till you want it. You can take it off any time.

UPDATED! Its version 1.1 now! Released and pushed to master!

- Added gutters both to arms and hub so arms wont be moved by thread - Arms is now two to fix the issue when thread falls off while extruder moving up - Added second arms model with different angle if your spool far from printer and first arm make some resistance
