Quick Release Filament Holder

thingiverse

This is a low friction filament holder which has been designed with a quick release hub. I wanted to create a filament holder which could sit on a table or mount on a wall, as a result I ended up with a design which traps the spool hubs bearings. I have included a Solid works file of the hub and latch to help in your designs. I may refine the design in the future as the bearing fits snug but loosens over time. Hub Assembly: 2 x 624-2r2 Bearings (13mm OD. x 4mm ID. x 5mm width) 2 x 4mm x 30mm Button Head Screw 2 x 4mm nuts Spooler Stand: 2 x 3mm x 16mm Socket Head Screw 2 x 3mm nuts 2 x 3mm washers 2 x 1/4-20 threaded rod 8 x 1/4-20 nuts 4 x rubber self adhering feet. (Optional) NOTE: The hub design was inspired by the Spool holder with bearings http://www.thingiverse.com/thing:467008 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 eventually they will spin freely... I ended up using a little tooth past to help sand the threads. Mandible Hub After printing the hub may have some rafting material along the bearing path. In order for the bearing to lock in place it is important to make sure the bearing can seat all the way in. Take the time to clean the path for the bearing. If you are having trouble getting the bearing to seat all the way down, then you could use a small handheld butane torch, to heat the seat and then press the bearing into position.
