Boeing 737 MCP Korry-like switch for simulators

thingiverse

I've been modeling this part for a long time, and my plans have shifted significantly from where I began. Print both pieces separately, then attach a tactile switch to the case - it only fits one way. Next, try pushing the korry button into place. I'm using these switches (tactile 12x12x8mm) without caps: https://www.ebay.com/itm/20pcs-Momentary-Tact-Tactile-Push-Button-Switch-12-x-12mm-x-8mm-4-Pin-DIP-w-Cap/321057620566?hash=item4ac0868256:g:A9AAAOSwBjdaOSPD You can also attach 2mm square LEDs to the button and connect them using JST-style connectors. Printing requires some support, but not too much if you want high-quality results. Print with the best quality possible. Update January 28, 2018: - I added a collar for a better connection between the MCP backpanel. - The corners are now rounded. - Internal size is now 17mm and outer size is 21mm. - The tactile insertion window has been reduced. Update January 21, 2018: - I cleaned up the casing model to improve print quality. Update January 18, 2018: - I downscaled the button slightly. - The led holes have been increased in size. - Unnecessary clips on the casing and button were removed since the tactile switch has enough holding power. - The width of the casing bottom has been increased.
