Radial filament guide for cabinet mount

prusaprinters

<p>This is a filament guide designed to ease the path of the filament and prevent it from over-bending.</p> <p>I've put the 3D printer into a cabinet and feed the filament from the top and through the side (as seen below the guide). I was using a PTFE bowden tube as a guide previously, but since the spool is on top of the cabinet, I needed a support structure to avoid pulling straight down.</p> <p>Turns out, this simple guide without the PTFE tube entirely reduces the friction by more than half, since a minimal increase in tension will cause the spool to unroll immediately, without letting the filament touch the guide most of the time.</p> <p>There are two parts: the guide, and a small clip that snaps on top which prevents the loose filament to exit the guide. The clip is open, so the filament can be inserted from the side. I used weak double-sided tape to affix the structure to the side of the cabinet.</p> <p>I use this <a href="https://www.thingiverse.com/thing:2791247/">https://www.thingiverse.com/thing:2791247/</a> spool holder (another TUSH variant) sitting on top of the cabinet, combined with these hooks <a href="https://www.thingiverse.com/thing:2923602">https://www.thingiverse.com/thing:2923602</a> for the display panel.</p> <h3>Print Settings</h3> <p><strong>Rafts:</strong></p> <p>No</p> <p class="detail-setting supports"><strong>Supports: </strong> <div><p>No</p></div> <p><strong>Resolution:</strong></p> <p>Any</p> <p><br/> <p class="detail-setting notes"><strong>Notes: </strong></p> </p><div><p>No infill, supports or high precision required for this support. Print flat to have smooth layer lines in the direction of the filament.</p> Sand lightly the bottom pads to have good adhesion prior to taping/gluing. </div></p> Category: 3D Printer Accessories
