TAZ 40mm Hex Fan Mount

First, thanks tmorris9 for all your work on the original design. (http://www.thingiverse.com/thing:845113) I've been having problems with heat creep, so I was in the market for a more powerful heat sink fan for my new TAZ 5. I really like tmorris9's design, but wanted to clean it up a bit. Other than slightly cleaner geometry it's the same part. I'm still waiting on my fan so I haven't been able to install this yet, but tmorris9's design seems to be working for people. If anyone has trouble with my remix let me know and I'll try to fix any issues. Printer Settings Printer Brand: LulzBot Printer: TAZ 5 Rafts: No Supports: Yes Infill: 100 Notes: You could probably print with less infill, but it's a relatively thin walled part anyway, so why not make it solid. Post-Printing Just as a double check on the scale, the model should be 40 mm x 51.2 mm x 29.35 mm. Print with support. It's best to use ABS to avoid issues with heat. To install the fan mount remove the left bolt that holds the hot end in place and snap the fan mount over the heat-sink. Replace the bolt to secure the fan mount, then attach the fan. To install the fan, remove the tiny heat-sink fan and replace with a 40mm 5v fan. There are probably a couple ways to do that, including buying a part from Lulzbot, but here's how I did it. Remove the stock fan. I pulled the pins out of the harness to make them easier to work with, but you don't really have to. Cut both the wires on the stock fan and the new fan at about the halfway point. Solder the stock red to new red and stock black to new black. My fan had an extra ground wire that I just capped off since you don't need this wire. I didn't have any shrink wrap, so I used some of the original fan, which came with a bunch of extra connectors. It was a bit too big so I doubled it up to help get a tighter seal. This is how it looked loose. I used more of the shrink wrap from the new fan, and some of the sheathing to cover the rest of the wire. The sheathing wasn't big enough to fit around the new joints so I split it so it would fit over as much as possible and finished it off with some electrical tape. Finally, I installed the fan, ran the wires, and re-inserted the pins.
