((updated)) Hi-flo directional cooling duct for duplicator 4s ((

pinshape

I added a 10-degree tilt to the cooler and lowered the attaching point for the cooler on the arm by 1.50mm to keep cool air off the head and more aimed at the extruded filament. When I have another day off, I will rework it in ABS to bring it tighter to the carriage. For now, this thin PLA won't melt at this distance. I've been disappointed by cooling options for these style printers due to lack of room, so I decided since I had a day off, I might as well try to solve that problem. Well, here you go - print with PLA. For the Duplicator 4S, if you want good cooling for PLA, take off the front panel and side window. I designed these directional coolers that work amazingly and are very light. The front face has to come off, so sorry 4 and 4x users. Coolers are directional for great spread of cool air across extruded filament. Instructions: must rotate and sit flat on fan mount to print. I printed this in PLA at layer height 0.10, shells 2, infill 0.1, speed 20 - keep it slow! Very thin wall. No raft or support. First, install the bracket with the fan to the extruder. Then, install cooler to the bracket (I used very small M3 screws that came extra with my printer).
