I've recently come into a dusty old Cupcake and I plan on optimizing and modernizing it as much as possible, while keeping the iconic look. This replacement panel is made to mount a Sanguinololu board, instead of whatever relic you currently have running your cupcake. I will probably revise it with updated endstop holes when I figure out what I want to do with them.Laser it. Install it. Enjoy it.
