Part Cooler for German RepRap (GRR) Protos V3

thingiverse

This is for the absolutely ancient Protos V3 3D printer, as the version i "inherited" from some other students at my school who built it from a kit some years ago did not have any part cooling. To make this mod fit properly, i had to remove the second nozzle and nozzle heater, i will probably remove the second extruder motor soon as it is broken anyways. On top of that i removed a piece of sheet metal which i believed to be meant as a heat shield, but barely got hot during Printing and replaced it with a printed Bracket to hold the Belts in place. This attatches only by sliding over the piece of sheet metal that usually comes out of the front of the Print head probably to protect the stepper cooling fans from heat. I made the Slot in the "Main" piece a bit bigger than i needed to and put some tape over the sheet metal until i achived a snug fit. "Fan Holder" is Snap-In-Place style for fans with outside dimensions 80x80x25.5mm -4 Holes, 4.5mm in Diameter, Hole centers 71mm apart. (i believe this is a standard fan size, but i have not checked. Mine is out of a Pile of old computer and server parts) I marked this WIP because i have not tested this extensively enough to recommend printing yet. Contact me if you actually have this printer and want to make this mod yourself ;)
