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 had the same experience. While I was very happy with the “clickyness”, the color and the feel, it just takes to long to produce enough parts (FDM with 0.25mm nozzle and 0.05mm layers)
