Springy Spiral Spool-hub Desiccant Holder

prusaprinters

<p>Holds desiccant. Stays in filament spool hub for a wide range of hub diameters (about 55 to 75mm).</p> <h3>Print instructions</h3><p>I printed in 0.6mm nozzle but 0.4mm should be fine.</p> <p>I used clear PETG and filled with orage/green indicating desiccant.</p> <p>I'd be interested how well it works if anyone makes with PLA.</p> <p>Cylinder modifier is added such that the top and bottom are only grid infill -- no solid top/bottom layers on the inner portion. This makes a permeable membrane to hold in the desiccant.</p> <p>Pause print near the top to add desiccant. Once the print is done, the desiccant is permanently inside.</p>
