A300 thin case

Thin case for ASRock A300 motherboard.

Dimensions for case are 150,9mm x 143,5mm x 54,4mm(not counting height of screws or taped pads if used).

Case is meant for use with Noctua NH-L9a-AM4(or Intel variant, Intel motherboard compatibility not checked) cooler and M.2 drive(s) (bottom M.2 has no ventilation). No room for SSD drives.

Different top models for different lenght M3 spacer nuts.

No stress testing done, so depending of material, might heat warp in heavy use.

Print in pictures done with Middle_with_supports.stl and Top_6mm.stl, bottom.stl made 0,5mm thicker after printing for rigidity, but not test printed after model change.
