I had some clearance issue with my fan duct: https://www.prusaprinters.org/prints/37368-prusa-mini-mosquito-fan-shroud so I decided to make a low profile version of the heatbed cover.
I lowered the height from 4.8mm to 3.8mm to be in line with the 4mm screws to line up the heatbed. Also didn't like how the original cover slotted in together so decided to add screw holes to fasten the two covers securely. You will need 2 M3-10 screws and 2 M3 Nuts.
Printed at PETG 0.2mm Layer Height @ 15% infill. Provided GCode that prints them sequentially.
Print the top cover flat face down and the bottom one with the hexagons up. Refer to 3mf for orientation.
