This is a universal server rack ear fitting 20x20mm, 24x24mm, and 28x28mm bolt patterns. I based this off of the Linksys rack ear but made it a bit more universal since my Cisco Switch required a 28x28mm bolt pattern. I also made the 3 rack mount M6 holes into slots for a bit more wiggle room depending on the width of the equipment these go on.
You can use either countersunk or non-countersunk (Pan head) M4 machine screws with this design. The mounting holes for a server rack are meant for M6 machine screws but you can go a bit larger or smaller.
Print Settings:
Note: This should be almost solid, bump up the wall thickness before the infill so it's stronger.
Material: PLA+, PLA Pro, or PETG is preferred for the extra strength
Walls: At least 2mm thick
Top/Bottom: At least 1mm thick, preferably 2mm+
Infill: 20%+ (Make your walls + Top/Bottom thicker first)
