The Lack Enclosure Spool System (L.E.S.S)

Doing more with LESS (ok no more LESS puns). This system allows people using the Lack enclosure to quickly swap out spools of filament without having to take them out of their dry box or remove them from their open spool. It’s really just a simple bracket mounted on the top of the enclosure and interlocking brackets on various spool carriers. The video https://youtu.be/TTmMKfy4vtQ shows examples of it in use. Included files are as follows: • Bracket for the top of the enclosure (need three) • Bracket for a single spool dry box (I use the Rubbermaid 21 cup container) (2 pieces different size holes) • Large brackets that could work for a multi-spool dry box • An open air spool holder (3 pieces – left, right, and the cross brace) • A dry box pvc pipe holder with angled entry to not drop spool when in the angled up position (2 pieces – left and right) (through experimentation, I’ve discovered the plain, unmodified ones you might already have seem to work just as well) Note, the design is very simple and can should be quite easy to design brackets to work with other sorts of spool holders. For my dry boxes I put cork feet on the bottom after installing the bracket so it would sit level rather than put a lot of weight on the bracket. Print instructionsI printed my original brackets on the Lack table in PLA and most of the others in PET. While the PLA has held up fine, I think I’d print those in PETG if I were starting over today. I made the holes small with 4 perimeters so I could drill out to the size of whatever hardware I had handy. I’ve included another version with larger holes if you prefer it. Included some screenshots of printing orientation.
