Micro (running) Wallet

Many years ago, I designed the smallest wallet I could make. I have used it during every run and bike ride ever since. Until last week, it finally broke. So I just printed a new one and shared it here. Features:Holds my house-key and two cards (one credit-card or bank-card and my ID-card). All I need, when I go on a run. Hopefully your key will fit as well. Key recess 25mm x 58.4mm x 2.4mmI added the loop to be able to attach extra keys.I printed my original in PLA and it lasted more than 5 years. I printed the new one in PETG HF and it seems to work just as well. I also tried TPU, but it is too flexible for this design.Boost MeIf you like my design, it would mean a lot to me if you gave me a boost to support my work.Thank you!
