Ender 3 Filament Roller Guide w/ Z Axis Bearing Support

thingiverse

I originally printed both the Filament Roller Guide, and a Z Axis bearing support without thinking about the fact that both need to occupy the same spot on the upper rails. I've been loving the filament guide, but I still wanted to add the Z support, so I simply took both models and mashed them together in tinkercad. I did measure, so the z support should be in roughly the right spot, but I still need to print it to test. I didn't modify either file beyond combining, so the filament roller was designed for a 608 ZZ bearing, and the Z axis support was designed for a 608-2RS, but either one should work. **Just printed the first one, and added some pictures. Everything fits, and still left room for my Z axis knob. I think I will go back and ad a couple mm to push the Z axis away from the frame. . .it's not binding but looks like it's pulling the top in a bit. You'll also need the Ring, and Spacer files from the original filament guide/roller to be able to fit the bearing. ***I've done several prints now, including my tallest yet. Which almost maxed out my printer. No binding or issues at all. In fact the z-axis is super easy to move now.
