OTTO P1-1 push button replica

The famous (and expensive) P1-1 OTTO Pushbutton, super common on American aircraft controls, now replicated using a 6mm threaded tact button from Aliexpress and then 3d printed ring to go around it

This is the exact store page I bought the switch from, but the dimensional drawing will help you find alternatives that are the same size. (buy the 3 pin, the 6 pin is too large)

I've also updated one with a "hidden flange" where there is a 1mm lip around the edge and the tube is slightly undersized, for putting into holes where you want to glue it at the top and not have it fall through. (some B8 Grips)

Here is an instructional video on how to set it up
