I designed a Keyboard Cover for the Keychron V1 (75%) Keyboard fr portable use. It can be used without any magnets, but there are inserts for 6mm x 2mm magnets in-case you have those available and want to use them to make sure there is a stronger connection.
I printed this on an Ender 5 at the Desert Spark Innovation Lab (https://www.printables.com/@DesertSparkL_1922579) in Al Udeid AB, Qatar. I designed it to fit over a Keychron V1 75% Keyboard, and it makes an excellent cover to protect the keys while in transport to LAN parties or on airplanes.
The 2mm x 6mm magnets aren't required, but add a little bit of grabbing power to prevent the cover from falling off. I printed the cover in PLA, but PETG willl work too as long as you factor in the removal of support material. You can also use Prusa-Slicer's Negative SVG features to emboss text and/or graphics to the cover. You don't need tp add supports if printing upside-down
