This modification thickens the mounting platform, positions the slots so they are dimensionally the same as the Sovol SV06 screw holes, and instead of using a third printed plastic insert for friction fit, I've made the ‘nub’ larger and angled so you can press the bearing directly onto it.
Please reference the original object for instructions/parts. There should be a link to the original near the bottom of this page.
