This is a forced cooling enclosure i created to suit the Gen 6 electronics. The fan duct is glued onto the main cover as im too lazy to change it to a snap on, plus glued could have several advantages.The cover snaps onto the base and a 40mm fan is attached to the fan duct. This creates a wider higher pressure flow of air for cooling in the important places.It provides good forced cooling keeping the board cool.Print all 3 parts. Mount base under Gen 6 PCB Glue fan duct to main cover Mount fan Snap cover onto base. Connect all electrical connections on Gen 6 board.
