Description
I need a solid card holder, easy to choose a card, secure, and less moving parts for durability. So I designed this.
The locking mechanism inspired by the Dango M1 slider. It can hold 9 cards without the front plate, and 7 cards with the front plate. You can scale the LR_center.stl parts up to accommodate more cards.
Front plate's function is to hold the latch in open position when you slide it halfway, so you can spread the the cards easily.
For the screw, you'll need 5mm M3 X 16. Thin head one will work best.
Optional one sided RFID blocker plate is included, I used copper foil used for electric guitar shielding, aluminum foil should work too. See image for clearer installation.
.step file included for easy tweak.
