Miếng Đệm PCB Silakka54

With this spacer plate, your top plate (that you attach the switches to) does not float.

Important

The final height of this part should be 3.3 mm. I got to this figure by measuring the gap between the PCB and the switch plate after I installed the switches without the spacer plate found on this page. I'm not sure how important this height is, but it was important to me.

I'm using MMD Princess V4 Switches in case that helps.

Check resulting print height

You might want to print TEST_plate.3mf which will only print a tiny portion of the full part. Measure the actual print, and scale the Z height in your slicer if you need to adjust.
