Ender 3 v2 Top Filament Roller

Update: This design is superceded by my single-roller design over here: https://www.thingiverse.com/thing:5330621

This is an alternate top filament guide for this thingy: https://www.thingiverse.com/thing:3428924/files . You will need two spacers and a bearing ring from that design to use this filament guide.

It improves on the original design (for my setup) by raising the top guide wheel rather than sticking a long way out to the side to avoid the top and bottom guide colliding on tall prints. This makes a more compact layout that works well with my rear filament spool mount (https://www.thingiverse.com/thing:5244806).

I have included the OpenSCAD file so you can tweak the dimensions to suit your printer setup. I am open to requests for change and suggestions for improvement.
