Expandable Filament Spool Holder

myminifactory

This simple and effective spool holder design lets you mount a filament spool anywhere you need it. The design began as an attempt to come up with something great for 3D Printing Nerd's design contest, but has evolved into a replacement for our current holders. The design consists of two models: a bracket that needs to be printed at least twice for the most basic version, and a dowel or rod that clips into each bracket to hold the spools. These models are expandable - just print one extra bracket and dowel to upgrade to holding multiple spools. This can be done as many times as needed, provided you have enough space. The models were designed to be printed without supports, so they're ready for use straight off the printer. I recommend printing at 0.2mm layer heights, but feel free to try higher if it won't cause issues with the small indents needed to clip the dowel to the bracket. If you print this design, I hope you enjoy using it without any problems. If you have feedback or suggestions, I'd love to hear them. I also want to thank 3D Printing Nerd for hosting the contest that inspired this design, which I'm proud of.
