Lacroix MBS wheel bearing spacer

thingiverse

Simple 23mm tall cylinder to use as a bearing spacer for Lacroix skateboard prototypo with MBS wheels. After printing make sure your spacer is 23mm tall. It's a bit wider than the axle so that a small deviation in extruder output will not make a difference in the fit onto the axle. Put the bearing spacer between the bearings in each wheel, then mount the wheels. Tighten down until the bearings BOTH seat flush with the wheel. This ends up crushing the plastic bearing spacer a bit, for a perfect fit. If you removed the spacer after fully tightening, you will see it gets crushed a bit to a length of around 22.7mm or so (+= .2mm). NOTE: If the wheel can be moved in/out along the axle, and you see the wheel slide on the bearings (ie, they go in and out of their pocket a bit), and this means it's not tight enough yet. There will be no play once the nut is tightened correctly. Make sure the wheel still spins freely. IF it does not, you've done something wrong. Check the make sure the spacer is 23mm. If you don't want to print your own, a set of 4 spacers in carbon-fiber infused PETG will be available to order from www.land-surf.com I printed with .2mm layers, and a .4mm nozzle. Variations on these measurements are fine. Just check your results with a micrometer (length is the important metric).
