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.
I know it’s not the point of the post but I still wanted to mention PrintABloks
These are made specifically for 3d printing and I just think they’re cool and better for our community :)
