IO Shield

outer width x length - 162mm x 50mm (motherboard side)
Inner width x length - 158mm x 45mm (part that sticks out of the back of your case)
overall height - 5mm (1mm inner side, 4mm outer side)
Mesh thickness is 0.6mm(easier to cut and still strong enough)
Has little clips sticking out to make it fit and stay in the shield slot.

I print this at 0.2mm layer height on 50% print speed. this can also be printed at 0.3mm layer height but i have found that 0.2mm works better as it does 3 layers
