I needed an eraser shield for a quick drafting project, but couldn't find one at home or nearby store, so I made one. I used pictures of most common eraser shield patterns online for reference.

Default height is 0.4 mm, but You can resize it easily in the slicer.

Print it 0.4-0.6mm thick, anything higher makes the gaps too high for the eraser to work through.

Prints well with PLA on stock Ender 3 v2
