30 degree angled spool holder 2020 kossel mini

prusaprinters

<p>I wasn't satisfied with the stock acrylic spool holder that came with the 2020 kossel mini kit from folgertech. It was sticking out quite a bit more than needed, and made of two parts. Additionally I wanted to feed the extruder motor (which I mounted on the lower rail with a bracket I designed for that purpose) in a more direct path, so the arm is rotated 30 degrees.</p> <h3>Print instructions</h3><h3>Category: 3D Printer Parts Summary</h3> <p>I wasn't satisfied with the stock acrylic spool holder that came with the 2020 kossel mini kit from folgertech.

It leaves a little bit of a rough surface but that doesn't affect unwinding of the spool at all.</p> <h3> Post-Printing</h3> <p><strong>Mounting</strong></p> <p>When mounting this, it snaps on the rail. For added security, I used an allen hex key in the channel behind the holder to keep a T-nut at the right height, then screwed in an M3 bolt.</p>
