Coin Flask Quarter Holder

prusaprinters

<p>I found that people didn't have a decent way of carrying large amount of quarters around the local arcade. In most cases, they would either keep them in the plastic cups provided by the bar or dump them into their pockets. I wanted a print that would be durable, secure, and wouldn't suffer from degradation from use (e.g. living hinges that break or require exotic filament, tabs that wear down). I also wanted the whole thing to be a single object so parts can't get lost. Holds at least $10 of quarters (maybe a couple extra) and dispenses 4 coins at once when tipped sideways.</p> <p>The Coin Flask is actually printed in separate parts. First, the "Cuff". Then, after the majority of the thread is printed on the "Flask", pause the print and thread the cuff in place. This traps it permanently.</p> <p>If you're really gutsy, you can print both parts at the same time, pause, then remove the Cuff and put it on the Flask. If your bed adhesion is good and your clearance tolerances are tight, it shouldn't be that hard. Plus, you can mix and match the colors without complicated upgrades!</p> <h3>Print instructions</h3><p>Print the "Cuff". Then print the "Flask" upside down (the slot closer to the bottom) with a pause at around 30-32mm height. You can use a filament swap or just a simple pause. Carefully thread the cuff onto the flask. Make sure the cuff is oriented with the slightly tapered side down, or it won't mate correctly with the interior geometry. When finished, clear out the support fins with some pliers and/or small file.</p>
