PC4 Plug with Filament Clamping

prusaprinters

<p>The plug can be used to close PTFE pneumatic tube fittings when not in use. For example, on a modified RepBox this can be used to avoid humidity entering the box. the plug has an inner cone which will clamp onto filament when inserted. This way, filament can be hold when not in use, and easily pulled out with the plug on removal to load into the printer. The plug's grip is formed to ease pushing the fitting mechanism.</p><h3>Print Instructions</h3><p>This requires good adhesion, I had success with the Satin sheet, the textured sheet didn't always work. The attached print file contains a set of 6 plugs for a RepBox. To avoid stringing with PETG (which disturbs the fit in the tube fittings) and to avoid ruining all plugs if there is a problem with one, the attached print file uses the experimental option to print individual objects. It will finish printing a plug before moving on to the next, the placement has been chosen carefully to avoid crashes.</p><figure class="table"><table><tbody><tr><td>Printer</td><td>MK3s+</td></tr><tr><td>Filament</td><td>Prusament PETG</td></tr><tr><td>Infill</td><td>100%</td></tr><tr><td>Supports</td><td>None</td></tr></tbody></table></figure>
