Costco Gear Bearing

The first pic is Geeetech Silk PLA Filament A-silk-silver, it is absolutely stunning. I printed normal pla temp and speed, end 200, bed 60, speed 50. Second pic is Solutech silver metal PLA. This is a remix of 'Yet Another Gear Bearing' by DrTomFlint. I followed his instructions to make a blank one then wrapped the Costco logo onto it with Onshape. I've included some blank gear bearings so you can do the same. Took 14 hours to print on Ender 3 v2, Dynamic quality (0.16mm layer height), 5% gyroid infill, adaptive layers, supports, Solutech silver metal pla. To break the gears loose, keep pushing hard on each gear with your thumbs, alternating sides. Eventually you will hear them cracking as they break free. It takes me a few minutes to get them all free. Quick dips in really hot water will help, start with just a few seconds and only dip the gears that are still stuck after pushing.
