Here it is mounted with the red letters
I wanted 3mm plate, but I got 1mm instead. I got it done for free so I can't complain. It is sturdier than I thought, but I'd prefer even sturdier since the shifter tends to kick back after I let go. This does put some force on the steel.
I'd be willing to share the DXF for some clear red acrylic and red SMD LEDs lol. Assuming shifters have the same travel distance, you should only have to move the gates to the right location.
