Ender 3 V2 Motherboard cover for 92x14 (noctua NF-A9x14) and 92x25 (many brands, noctua NF-A9x25) fans

A remixed to fit 92x14 (noctua NF-A9x14) fans and along with another version for 92x25 (many brands, along with noctua NF-A9x25) fans. Pictures above are for the 92x14 version. There's also screw posts for a second buck converter, for if you want to switch to dual 12v fans (like noctua ones) for part cooling. I wouldn't use a 12v noctua for the hotend cooler due to a lack of cooling potential to avoid heat creep. The .f3d files are (now) set up to be easy to change the fan size - the mounting holes will automatically be placed in the right spot for standard fan hole positions. Changing the height might be a bit more tricky. See the thing I remixed for printing instructions: https://www.thingiverse.com/thing:4653994 IMPORTANT NOTE: if you're using the 14mm version you'll need to remove the screw offsets for the buck converters (either in cad or with some flush cutters post-print), otherwise one of them will hit the aluminum extrusion. You can still print it and use one converter without any modifications needed).
