Riser and Dust Filter for Xfinity XB7 | CGM4331COM | TG4482

10/28/23 EDIT: Honestly, I don't think there's a noticeable difference without adding an external fan, and the dust filter doesn't seem to do anything either. *Anything that comes with a fan should come with a filter.* **Why?** After receiving my XB7 as an XB6 replacement, I figured I'd protect it from dust this time. The XB6 was also notorious for running hot, so I figured elevating it a bit and preventing it from getting filled with dust couldn't hurt. However, the XB7 doesn't seem to suffer from heat issues as much, so I'm not sure if this will actually improve temperatures at all. The airflow doesn't ***seem*** to feel any worse when the router is on the stand vs in midair. **Resources** I used OutwardB's fan grills script to generate the filters, I had to edit line 395 to remove the screw holes, and 1360, and 1361 to get the 0.9 mm spacing I wanted. If you download the SCAD, also download the JSON to the same folder to use the [customizer](https://i.imgur.com/eMfqTpE.png) preset. **What to expect** The dust filter [isn't actually a mesh,](https://i.imgur.com/JWvQ5H6.png) I just generated a grill 0.2 mm thick and stacked it 5 times in my slicer. I did this because it shaves literal hours off the print time, as slicers seem to want to print each square individually. However, the downside is that the layers aren't well bonded, and the entire filter will unravel if you put too much force on it. You're going to need [a perfect first layer](https://i.imgur.com/itf6yE5.jpeg) if you want any chance at a successful print. I recommend buying one on [Amazon](https://www.amazon.com/dp/B07LG1ZKB1) if you don't think you can get the first layer good. I also added a version if you want to add an external 92 mm fan to the router, but I don't think it will be necessary, or even that helpful due to the filter. Unlike [mturini's](https://www.thingiverse.com/thing:5708405) design, mine requires supports or high confidence in your printer's ability to bridge. I personally didn't use any, and you can see how well my undersides came out as a result. A better part cooling fan probably could have helped. I added 4.4 mm screw holes, but I never actually designed for them to be used, as gravity *should* be fine in all cases. (not sure how you'd use them with a fan, for example) **The router will stand 23 cm (~23.5 for FV) tall with this riser attached.**
