I needed a Dustcover for the Neutrik NAUSB-W on my CNC Machine, so i quickly built it parametrized with FreeCad.

I've printed it on my MK3s with PETG with the 0.2 speed profile on a 0.4 nozzle and it fits perfect. If you need other sizes, you can simply edit the spreadsheet in the Freecad file and export it again.

Info: The 3d Model of the NAUSB-W that is included in the Freecad file belongs to Neutrik, therfore this is not licensed under GPLv3. It's gathered from https://www.neutrik.com/en/product/nausb-w
