Tivo Bolt cooling adapter

**Update 30 Mar 2020:** Another great comment by [openscadder](/openscadder) regarding the fan - Noctua makes a 5V version of the fan which can be powered from the TiVo's own USB connections! See the comments section for more. **Update:** Make sure you take note of the comment by rscottbutler in the "Comments" section! A coworker of mine has a Tivo Bolt. Apparently, the stock cooling on the Tivo Bolt is not enough, and there are a bunch of folks who do a bunch of different things to improve the cooling. He approached me about making something to fit the Bolt to improve the cooling by integrating a larger fan than the tiny 40mm fan installed in the unit. He was also hoping for something that would work with the strange bent design of the Bolt. Here's what we came up with over a month of prototyping and testing. This is designed to use as little as plastic as possible while also requiring as few supports as possible. (see Print Settings for more details on supports) To use this, you'll need an 80mm fan and four M4x35mm or M4x40mm screws. The female screw threads are printed in, so put the fan in place, screw it in, and attach it to the power supply. In testing, Mark was seeing temperatures as much as 9°F cooler. **Update:** To check your before and after temperature, go into Help... Account & System Info... System Information and look for `ODT Temp` - keep in mid that this is the "On-die temp" for the CPU itself so it will be much higher than room temp, but it's good for a before/after comparison.
