Bearing Break-In Fan

thingiverse

Quality bearings are highly subjective. While expensive, high-quality oil or greaseless bearings might be overkill for a fidget spinner, they're perfect for this application. Instead of wasting money on premium bearings and then stripping them of their lubricant, why not add some clean wear to cheaper ones? Simply attach the main peg with the bearing and cap screwed in, then push the fan down onto the bearing. Take the entire mechanism to your car, roll down the window halfway, and slide the mount onto the back end of your window. Roll up the window to secure it in place and drive around! After driving to work and back for two days (approximately 40 miles total), I tripled my spin times. I've noticed that the bearings I've used tend to become more polished over time when placed in this fan apparatus. I also experimented with using toothpaste to see if I could achieve an even better spin, but so far, clean and dry appears to be superior to using toothpaste or another hydrolyzed silica compound. Printer Settings Printer Brand: Wanhao Printer: Wanhao Duplicator i3 V2 Rafts: No Supports: No Resolution: 0.2mm Infill: 40% Notes: I've only printed this using PETG, and in its current state, it taps on the window a little bit. If you use a more brittle plastic, it may break at high speeds.
