We've developed a simple little panel for attaching our favorite style of panel connector... the GX12.

This design is available here: https://pwncnc.com/products/onefinity-elite-snap-in-cover

It snaps right into place on the back of the Onefinity mounting panel.

Pictured below is my own Onefinity Elite Woodworker with our Tool-setter inlet port as well as our ATC inlet port already installed.
