Filament Spool Roller with Assembly Tooling

thingiverse

Remix of a great original design. Creation of a split roller component to allow for printing of these rollers. This does away with the need for a wooden dowel to attach the bearing to the PVC Pipe. I also made the pin which protrudes through the bearing a bit longer to prevent the bearing from rubbing on the sides. 8 of these are required for each assembly. Use of a small brim (I used 1.5mm) to help with bed adhesion of these split rollers is recommended. Length of the PVC pipe and concentricity between bearings is also critical. After cutting the PVC Pipe sections to length, I taped them together and established the length with a benchtop sander. I developed a set of vice jaws that can either be used with a vice or can be bolted together using 1/4-20 bolts for gluing the PVC pipes to the ends. I made one out of wood to test the concept, but I have not used the 3D printed vice jaws. I plan to make more of these and will print myself a set of jaws for future assembly. I included some pictures to better illustrate the concept. Included pockets in the underside of the vice jaw overhang for installation of 8mm x 3mm magnets to hold the jaws in a vice. I also removed some material from the sides and ends to make for less material usage and faster prints.
