Lacroix MBS wheel bearing spacer

thingiverse

Simple 23mm tall cylinder designed specifically to function as a bearing spacer for Lacroix skateboard prototypes equipped with MBS wheels. After printing, verify that your spacer measures exactly 23mm in height. Its slightly wider diameter ensures that minor variations in extruder output will not compromise its fit onto the axle. Position the bearing spacer between each set of bearings within the wheel, then proceed to mount the wheels. Tighten until both bearings are seated flush with the wheel's surface, resulting in a slight compression of the plastic bearing spacer for a precise fit. If you remove the spacer after full tightening, you'll observe it compresses to approximately 22.7mm or slightly less (with a deviation of about .2mm). Note: If the wheel can be slid along the axle and appears to move in and out of its bearings, indicating play, it's likely not tightened sufficiently yet. Once the nut is properly secured, there should be no movement. Ensure the wheel continues to spin freely after installation. Failure to do so suggests an error in the spacer height or mounting process. Double-check that the spacer measures 23mm accurately. For those who prefer not to print their own spacers, a set of four carbon-fiber infused PETG spacers will be available for purchase from www.land-surf.com. When printing, use .2mm layer thickness and a .4mm nozzle. Variations in these settings are acceptable; however, ensure your results are verified with a micrometer, focusing on the length measurement to guarantee accuracy.
