+## 3D Models

+As usual I try to minimize the need for support and only the top case needs them for where the screws go. Choose whatever infill percentage you desire. The top cover screws are M3 which are used by CD drives and floppy drives. The side and bottom screws are sized for standard #6-32 UNC screws used to mount hard drives. The holes are tapered to help tapping the holes with the screws.
