Printrbot Simple Metal Cooling Fan Duct

thingiverse

Adam here, with a hastily crafted yet functional design that I'm excited to share. After an exhaustive search for a cooling fan duct that would fit my printer's Ubis 13s hotend, clip-on extruder cooling shroud, and blower fan, every option fell short due to their inadequate piping lengths, oversized hotend rings that compromised print quality, or mismatched designs. I took matters into my own hands and created a custom solution that works beautifully. Although I was somewhat lax in measuring the exact angle of the fan bracket on the Simple, opting instead for an approximation borrowed from another design, it still proved to be effective. If you're facing a similar setup conundrum and need a reliable duct solution, this might just do the trick.
