There is a lot of talk about the switch not centering.The window switch parts require a rather expensive 3D printer to manufacture them accurately enough. Which process did you use? You might be able to file your specific parts to make them work. Another option would be to get the outer part printed slightly larger (e.g. 1%) and hope it still fits in the switch button. An easier option, however, is to get the parts printed on a higher quality machine. Back when I still sold this part, I used a $30,000 printer and didn't have the issues you described above... all my issues were on the customer side .
Mudder recommended increasing the size by 1%. I'm wondering if I should possibly order a second spring detent at make it 2-3% larger this way I can file it down to hopefully avoid the centering issue of the switch.
Does anyone know what part mudder is talking about when he says outer part? Is this the spring detent or the light pipe that should be ordered larger?
