Taz 5 40mm Hexagon Fan

thingiverse

This is a replacement for the inadequate little squirrel cage fan on the Taz 5 Hexagon Hotend. There's a Taz 6 mount available, but I didn't want to have to print the entire assembly just to get a better fan on the vanes. This simple solution should help more people than me, and it required no modifications to the Taz other than wiring in the new fan. It takes a 25mm M2 bolt with washer to mount to the original cage fan hole, or you can do what I did - order 20mm bolts by mistake and have to drill out 5mm of the hole to make it fit, but that's not recommended. I had originally linked to a fan on Amazon, but that one ended up sucking, so I removed it from the description. Any 40mm 5V fan should work as long as you keep the current rating at or below 20ma and everything should be fine.
