PTFE Tube Cap with Filament Holder

prusaprinters

<p>I have a drybox that uses PTFE tube to route the filament to my printer. When not in use, I needed a way to cap the PTFE tube to keep moisture from getting into the box. I also wanted something that would grab hold of the filament so that it doesn't go back up into the tube, requiring me to open the box.</p> <p>While there are several PTFE tube caps available on Thingiverse, I only found one that also captures the filament. However, it didn't work very well. I created my own design that has some flexible arms inside the cap that will latch onto the filament.</p> <p>2018-07-30: Updated to fix issue in F360 source file, to reduce wall thickness, and to parameterize a few things.</p> <h3> Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>Prusa</p> <p><p class="detail-setting printer"><strong>Printer: </strong> <div><p>i3 MK3</p></div><strong>Rafts:</strong></p> <p>No</p> <p><p class="detail-setting supports"><strong>Supports: </strong> <div><p>No</p></div><strong>Resolution:</strong></p> <p>0.2</p> <p><p class="detail-setting infill"><strong>Infill: </strong> <div><p>Optional (see text)</p></div></p> <p><strong>Notes:</strong></p> <p>I printed this all perimeters, but it should also work fine with infill. I recommend using a filament that has some flex to it (PETG is a good choice).</p> </p></p></p> Category: 3D Printer Accessories
