adjustable filament reel roller

thingiverse

Now upgraded to Mk3, I've strengthened certain areas and added a lip for easier disassembly from its bed. Unfortunately, I broke one of the last models when trying to remove it. Updated versions based on Mk2 are now available, with two configurations: A features holes that allow filaments to pass through freely, while B has holes for thread take-up screws. The bearing screw has been recessed, making it harder to adjust the length screw. As a result, M12 bolts will be needed from now on. I've also designed an adjustable filament reel roller as I own several different brands of filament, and each one requires its unique size adjustments. For this purpose, screws are provided in M4 X 40mm length, along with 10 x 4 x 4 bearings, and about 1mm thick M4 washers to keep them in place using M4 X 16mm allen bolts. Here's the Instructions: Instructions were printed out in PLA at 0.2 layer and 30% infill setting. The bearing support holes have all been tapped to match M4 thread specifications. To be precise, half of the holes are drilled out to a 4mm diameter and tapped accordingly to fit standard threads, while the other half follows standard threading procedure.
