SELF-CENTERING FILAMENT HOLDER ASSEMBLY GUIDE
x4 608 bearings (included in Universal 3D Printer Enclosure kit)
We added some grooves to add friction so that the roller would spin with the filament spool.
There's a hex rod that connects the two bodies together in the middle, which allows you to print these pieces in the optimal orientation.
Please print in the orientation shown below for the best results.
Add the 3 inserts to reinforce the filament roller.
The two sides have interlocking features, so the easiest way to assemble them is to add both rollers to one side first. Make sure the bearings are in place.
Add the other side and ensure all pieces are aligned correctly.
Add the interlocking hex piece in the center. The hex fits snugly, so you may need to apply some force.
Now you are ready to roll!
