Custom card holder

A custom card holder I made for myself, features-

- A slot on the top panel for a semi-permanent set RFID card for subway train scans
- Storage for key and sd card-sized items below the top panel
- Actuating top panel with left hand makes 5 cards slide up from top opening
- Final card in the back, with a slot at the back to access swipe strip on card, for use with College ID

Print and stack according to pictures, use 4-40 screws, 1/8in dowel, and superglue to assemble.
