(Revised) Filament Guide for Ender 3 PRO (with roller) with bearings

thingiverse

Honestly probably unnecessary, possibly worse. ShamloK guide is great as is for an ender 3. But i wanted to start learning how to use Fusion 360 and have a pile of 608 bearings kicking around. This is my first design/remix in Fusion so any tips or improvements i could make are welcome. Remix is adding cups to the roller to house the 608 bearings. En-biggened the roller area and axle to make everything fit. Modified robathome's spacers to fit the axle. Should be able to print the arm and spacer can print without supports. I found printing the axle laying on the bed with a brim the most successful way to print it. Standing would start wobbling and print poorly: no brim had a really hard time with adhesion. Roller with supports. I used tree supports and it worked great. Fitment may be a little tight, a little corrections with de-burring tool or sandpaper should get you good.
