Open Air Frame PC Case

Minimal design to fit ATX, mATX and ITX motherboards with ATX power supply. Board mounts upside down.

Allows for one 2.5" drive to be mounted above PSU. Drive should be mounted before PSU and motherboard.

PCI bracket holes will have to be added manually. I have added a larger bracket that is printed in 2 parts for ATX motherboards. The long part can be printed diagonally.

Insets can be used for more stability, but works fine as is. I used door knob screws on my build (4mm x 35mm). Might need to drill openings a little wider for easier assembly.

PLA Filament

Layer Height: 0.42mm

Line Width: 0.64mm
