In a 1980's arcade cabinet with a metal control panel, the leaf switches were mounted with two plastic ring spacers under each switch to make them the right height for the buttons. I measured the spacers and created a spacer that extended out past the switch terminals to facilitate anchoring wires to it.

The other spacer STL file is for adding a second spacer when using longer switches.

I used PLA and draft mode since sturdiness and appearance aren't really an issue.
