Tinyboy / Fabricator Mini 1.5 Part Cooling Fan

thingiverse

Part cooling fan for TinyBoy Fabricator Mini. I had the idea from a part seen here, but unfortunately, I didn't save it and now I'm having trouble finding it again. If you're aware of this or are the original author, please let me know so I can remix it correctly. To install the fan, you'll need to run an extra pair of wires and connect them to one of the free terminals on the board, then reconfigure and recompile your firmware accordingly. The fan duct is attached with the lower 2 screws of the hotend radiator fan. It's designed to be shallow and skinny, allowing it to fit under the arms at Ymax without reducing Z travel. You may need to reroute the heater and thermistor wires around everything to clear the machine internals. I found it easier to remove the hot end to snake the wires through and into the wire bundle. Tip: Print the fan on its side without supports. The little bit that sags will be inside, so you won't notice it. Depending on your additional fan, you might need to trim the fan duct a bit to get it to fit properly. The center tab should hold the fan in place.
