Both the RSA Badge Case and Plain Badge Case feature a spring to push out the third card while the other two slots are occupied. The RSA badge holder accommodates an RSA token in addition to 3 cards!
Print Instructions:
The plain badge case does not require supports. The RSA Badge Case model does, but only in one spot (Refer to the images).
Both models should be oriented in the way they were intended to be printed.
The spring can be printed in PLA. However, it's recommended that you print in a more durable material like PETG, ABS, ASA, or similar material. If printed in PLA, you'll have to replace the spring more frequently.
Assembly Slowly press the spring into the side of the case until it snaps into place. You may have a moment when you're questioning if you're pushing it in too far before it snaps in. Once you've reached that moment, push a little more and it'll snap into place.
