About this drill template
Drill template for the Aion FX Lumitron Resonant Filter, sized for a Hammond 125B enclosure (63.6 × 119.3 × 35.8 mm). The pre-positioned holes match the PCB's pot footprint exactly, with the footswitch centred below the 3-knob layout, with 3 toggles. Print at 1:1 scale, tape to the enclosure face, centre-punch, and drill. PCB and parts not included.
Aion FX description: “The very first commercial envelope filter effect, first released in 1972. Famously used by Bootsy Collins, Jerry Garcia and Stevie Wonder among many others.”

Print a drill jig for your own build
The editor turns a layout into a jig for the exact enclosure you picked. It fits snugly, so it stays put while you punch and every mark lands where your layout puts it. It marks the side faces as well, so the jacks and the DC socket are covered.
