Kwuad Spinner

thingiverse

A cleverly weighted spinner with knurled edge comes into view. This one boasts a color changing PLA which is some fun material to work with. Caps are not included, but are highly recommended - there are plenty out there to choose from, so pick your favorites and have fun spinning away. The white version is the same file without top and bottom layers, no infill and 5 perimeters. Print Settings Printer Brand: SeeMeCNC Printer: Rostock MAX v2 Rafts: No Supports: No Resolution: .3 Infill: .25 Notes: Done with 3 perimeters, 3 top, 3 bottom layers. The spinner uses 608 skate bearings to give it a smooth spin. The center bearing has the seals removed and no lube applied - even thin lubes can reduce the spin time. The bearing holes were carefully sized so minimal fitting is required, but a test object is included since printer calibrations can vary. Print it out first to check the bearing fit and if it's too tight or too loose you can scale it up or down by a small percentage. If you tweak the scaling for the test file, use the same scale on the real file and it should fit the same way. On my printer I only had to scrape the insides of the holes with a pocket knife to get a good snug press fit. This puppy spins nice and true for a long time even with the weight of the 4 outside bearings. Note: For some reason there are some phantom perimeter lines on the bottom layer - I don't know what's causing that, but it's probably something funky with the model, not yet figured out. I tried to use bottom clip to ditch them but they persist. It still prints okay, but you may have to shave a feather edge off the bottom layer perimeter if you don't use a top-bottom layer (the white skeleton version).
