Raspberry Pi Protoneer CNC Board Case Case made for Raspberry Pi2B and Protoneer CNC HAT Board Kept "over hang" on CNC board open underneath, to give axess to SD micro and abillity to fit a fan if the Pi and stepper drives needs it. I do not use the sockets for running internal stepper drivers, only external drives. Bottom case part have VESA footprint, so you could mount the thing on a TV or better, straight on the back of a touch screeen monitor :) All cred to Bert and Protoneer Co.NZ that developed the CNC board. This made the cigarette pack size computer and cnc unit possible. More about this at: http://blog.protoneer.co.nz/raspberry-pi-cnc-board-hat/
