Quick Release Filament Holder

thingiverse

This is a low-friction filament holder that has been designed with a quick-release hub for convenient use. I wanted to create a versatile filament holder that can sit on a table or mount on a wall, resulting in a design that securely traps the spool hubs' bearings. I have included a SolidWorks file of the hub and latch to facilitate your designs. I may refine the design in the future as the bearing fits snugly but loosens over time. Hub Assembly: 2 x 624-2R2 bearings (13mm OD, 4mm ID, 5mm width) 2 x 4mm x 30mm button-head screws 2 x 4mm nuts Spooler Stand: 2 x 3mm x 16mm socket-head screws 2 x 3mm nuts 2 x 3mm washers 1/4-20 threaded rod (2 pieces, 6 inches long) 8 x 1/4-20 nuts 4 x rubber self-adhering feet (optional) The hub design was inspired by the Spool Holder with Bearings on Thingiverse. Print Settings: Printer: Afinibot Rafts: Doesn't matter Supports: Yes Resolution: 0.1 Infill: 80% Notes: The supports are only needed on the threaded spooler shaft and the spooler sides. Post-Printing: Spooler Hub Assembly The threads for the spool hub and shaft may bind when first assembled. If you slowly thread the hubs on and off the threaded shaft, they will eventually spin freely. I used a small amount of toothpaste to help sand the threads. Mandible Hub After printing, the hub may have some rafting material along the bearing path. To ensure the bearing locks in place, make sure it can seat all the way down. Clean the path for the bearing thoroughly. If you're having trouble getting the bearing to seat properly, use a small handheld butane torch to heat the seat and then press the bearing into position.
