Drybox Filament Port For PC4-M10x1.0 Fittings

prusaprinters

<p>This is just another filament port for a drybox, with this one being for PC4-M10x1.0 fittings. It uses a compression fitting to retain a piece of PTFE tubing that "hangs in the breeze" to guide the filament into the coupling off the spool. I created the "nozzle" that extends into the base of the PC4 fitting because I found that by doing so it eliminated the filament catching on the plastic stop on the underside of the PC4 fitting.</p> <p>I printed with 0.1mm resolution due to the threads needing the extra resolution.</p> <p>The holes and nuts are M3, and 12mm screws work well for me and leave you a little space if you want to insert a gasket of some sort.</p> <h3>Print instructions</h3><p>I printed with black Hatchbox PLA at 0.1mm resolution with a 0.4mm nozzle using the Prusa PLA presets. The ferrules printed well enough for my use, but they're never going to look super pretty unless you print them with an SLA style printer.</p>
