Phanteks Expansion Cover

I recently decided to do a PC build for my niece. The Phanteks P300 case came without a cover for the expansion slots--which is alarmingly common. Fortunately, my personal rig has a Phanteks P350X, with the cover--used it as a template to create a replacement.

I designed it for use with 6x3mm magnets, but also added holes for thumb screws (if needed).
