<p>Do you want want a smaller more organized keychain? If your keychain carabiner should hold keys, a shopping cart coin and a bottle opener, then this design is for you!</p> <p>It's not larger than usual keychain carabiners, it holds a 1€ coin which slides out to be used for the shopping cart and it can open beer.<br/> Three functions (1. Bottle Opener, 2. Shoppingcart Coin and 3. Carabiner) in one BOSC³ (BottleOpenerShoppingCartCoinCarabina) and your keychain will be organized! If you like the design give it a ❤</p> <p>For the carabiner I used the compliant mechanism mechanism by Walter Hsiao <a href="https://www.thingiverse.com/thing:983879">https://www.thingiverse.com/thing:983879</a> - prints in one piece no assembly needed!</p> <p>There is a good location to put place a text or logo -follow this simple instruction to modify the STL with meshmixer: <a href="https://www.youtube.com/watch?v=JXt6grv2AeY">https://www.youtube.com/watch?v=JXt6grv2AeY</a></p> <h3>Print instructions</h3><p>The mechanism needs little flex - PETG with 25% infill works perfect.</p> <p>The design prints without supports! Although there are 23 mm bridges, but usually this is not a problem.</p>
