I had some missing LEGO bits, so I found the components on ldraw.org, converted to STL with LDView, and butchered them together with Fusion360.
In this case, I merged 3 parts into one, so I’d only have to deal with 1 interface instead of 5. The sanding probably made it worse.
Due to the relatively small size and overall complexity/tolerances required for the object, I wonder how it would have turned out if done on an SLA printer.
Yeah the tolerances on LEGO are high enough you really need a resin printer for good results.
