Printrbot + (Wooden) Fan Bracket

thingiverse

Old, slow, and inaccurate, my ancient Printrbot Plus is nonetheless my workhorse printer. While the cool, new machines are getting upgraded, the old PB just chugging. Why keep it? Because it's reliable, uses 3mm filament, and just keeps churning along. This old Printrbot never had a cooling fan for the extruder. When it wasn't too much trouble, I'd aim a desk fan at it. Lately, though, I've been experimenting with firmware, and thought a fan would be worth adding. This is a basic fan in two iterations, one with the mount on the side and one with the mount centered. It requires a standard 40mm fan, (3) M3 nuts, (3) M3 screws, and a mounting hole drilled in the wood of the extruder. It's not much, but it may be of use to someone.
