Removable Folding Spool Arm for Lulzbot Mini

When we built the enclosure for our Lulzbot Mini 3D printer, we needed to replace the stock pivoting spool holder, so we designed a bracket to mount a removable spool arm. The first version was just a hack (literally - we hack sawed the bottom off the stock arm, and made it removable, with the printable bracket we designed. We also made a printable version of this where we hacked off the bottom in OpenSCAD.

But we were never really happy with that solution, so here is an improved spool arm. This one uses the same bracket, as the old hack, but it changes the upper end to pivot and fold up for storage. We're really please with the final product. And, it is still printable, and we made it sow that both pieces fit on the build platform of the Lulzbot Mini. (the stock arm did not.) Now you can print your own removable-folding spool arm.

This project is part of our effort to improve our enclosure kit for the Lulzbot Mini. If your're interested, the kit is available at: https://
