I was tired of trying to remember which generic key fob matched with which door or lock around the house so I designed some more 'representative' key fobs and I can honestly say it has reduced my key-confusion significantly.
Printing:
I printed in TPU (75A), and since they are flat it should give you no grief providing your bed is mostly level. PLA would probably fracture around the ring as it is quite slim.
I ran with 40 % infill to add some weight and 3 perimeters to ensure strength at the ring. approx 20 minute print time.
