Parametric Bearing Cover

thingiverse

This is a customizable decorative bearing cover or dust cap (seal) I designed for 608 fidget spinner bearings. I wanted to be able to color match the bearing seal with the rest of the spinner - and I was unable to find one on Thingiverse. It has optional, customizable text around the circumference, an optional retainer ring, and optional inner and outer top rings. For a 608 bearing, I recommend a base thickness of .8mm and no more than 1.2mm overall thickness. The default parameters work well for a 608 bearing when printed at .2mm layer height on my Monoprice Maker Select (Wanhao Duplicator i3). I use the Cura Plugin "Change Filament at Height" to make the text a different color than the base (filament change is at .9mm in my photo). You can find it here: https://www.thingiverse.com/thing:2077884. This should be adaptable to generate a dust cap for any bearing size if you know the dimensions you need. Note that the default dimensions are for a decorative bearing seal. The bearing should "free spin" with this cover installed. If you want an actual dust seal, you will likely need to do a bit of experimentation and use something other than PLA. Working with text will take a bit of experimentation. You will need a "boldable" font (check fonts.google.com for the ones that work with Customizer) that completely covers the base surface if you want a prayer of your slicer being able to figure it out! I like Arial Black. I have included a generic STL with no text if you don't want to mess with the customizer. If people let me know this is useful in the comments, I might upload my parametric spinner cap as well. It also has similar customizable text features.
