Cardholder

Basically a simple cardholder that you can stick to a wall or door holding a card.
In my case the city decided that we should dump our waste in centrally located underground storage containers. Since you only get one card i needed a nice holder which allowed me to stick to my front door, so everytime i go out and dump the household waste i can take it from the holder and afterwards put it back.
Simple but does the job. Hold cards up to 2mm thick (my card was 0.78mm) but wanted to be able to take it out easily.
Openscad file included.
