Quad-offset Open Satellite Fidget Spinner (EDC)

thingiverse

This design was definitely inspired by http://www.thingiverse.com/thing:1957808. I'd like to thank Strabe3d for the original concept. The inner diameters are drawn at 22.1mm, so you may need to sand or use a vice depending on your printer's accuracy from calibration. It's designed right-handed, but if you're left-handed, just rotate the model on the X or Y axis before printing. Five 608 skateboard bearings are required to complete this model. Print Settings: Printer - Mini Kossel; Rafts - Yes; Supports - Doesn't Matter; Resolution - 0.1mm - 0.2mm; Infill - At least 30% or higher. Notes: I use Mattercontrol for slicing. The high infill on this is for structural stability within the bearing satellite holes, so play it safe due to their open nature. Use at least three shells or 1mm perimeter settings. I also use a raft at the moment, but have printed just fine without one, and the same goes for supports. Your slicer may not even see the need to place them. This is also true of the lower resolution preferences. You can get away with 0.3mm, but it's a small print anyway, and truly, you'll feel better in your hand. Test your printer's capabilities every chance you get. For absolute perfection, you may have to adjust your slicer's triggered retraction distance (perhaps 20mm down to 3-5mm) to help with stringing along the vertices within the finger slots. There are two speed settings in Mattercontrol that can significantly help with oozing: "travel speed for non-print moves" and "retraction length on move." These may have to go faster or slower depending on your results. Experimentation is the best teacher at this point. If successful and using Mattercontrol yourself (or Repetier, probably), make a profile to store your spinner settings, especially if you design and sell models. Whew, seems like a lot for a spinner! I might have an addiction... Post-Printing: Anything you may need to do? - sand? - use a vice? - glue? - acetone? - file? - bake the model? (I'm serious on this one; it's a thing.) (Although, I'm too lazy for that, it's still there. See last sentence.) - pick at burrs with fingers? - Netflix and chill? All choices are yours to make, not mine.
