Ender 3 and 3 V2 Filament Guide - GO BIG - No Screws - No Supports

No supports

No Screws (all parts and installation are just a simple press fit)

The extra deep groove dominates even the most unruly of filaments!

STL and FreeCAD files provided

For Ender 3 and Ender 3 V2

The bracket is just a press-fit onto the z-carriage, with moderate effort until it is seated. Firmly push the bracket all the way onto the Z-axis carriage (the cutouts wrap around the axle spacer and nut).

The 2 half-rings are a press-fit onto the bearings. You can just use your hand, but I found that using a flat surface helps to press the parts nicely onto the bearing.

You will need a 608 bearing (one of the most commonly available bearings, used for skateboard wheels and other things).

When installing on the printer, make sure that the Ender 3 (or V2) nut has one of its flat sides at the top. This will give you the clearance for a nice snug fit.

UPDATE: To help with modifications, in addition to the FreeCAD (original) files, I've included STEP files.
