Bearing - OpenJScad based new design

thingiverse

It's a brand-new bearing design that can be tailored to meet specific needs since it's written in OpenJScad. I encountered significant bed adhesion issues, so I uploaded two models - one with no raft and the other featuring a 1mm gap between the base and the bed. This forces the slicer to generate support, which also prevents the first layer from fusing together. **Print Settings** * Printer: RapideLite 200 * Rafts: No * Supports: No * Resolution: 0.2mm * Infill: 40% **Notes** First try printing the 'No-Raft' STL model. If it doesn't work, enable support for the 'WithSupportAsRaft' option and give it a shot. In my case, even with 0.5 times the nozzle size tolerance, I achieved great results using this forced raft. However, it only worked when I used the 'WithSupportAsRaft' option due to super bed adhesion issues. Normally, I configure 50% support fill when using a forced raft. **Post-Printing** If you use the 'WithSupportAsRaft' option: You'll need to sand the base for smoothness after printing. After sanding, it works like a charm! **How I Designed This** I was inspired by a 3D printed planetary gear and decided to take it to the next level. After successfully printing the planet-sun gear, I got this idea and designed it from scratch. Since the standard model for 608 bearing size proved too weak, I created my own design and was pleasantly surprised by its strength and output. In OpenJScad, I started with a 2D model and then used rotate_extruded it as a bearing. My hope is that this will be useful to someone out there!
