Introducing the Joel Holder.
Designed for Joel Telling's Spool Holder 3D printing contest.
An extremely simple, single piece spool holder designed to hold a spool of filament on a 1X2in board. Being that all things 3D printed are iterative, this spool holder is inspired by the Prusa MK3 spool holder, but completely redesigned from the ground up for proper weight distribution mounted on a board. In holding with the spirit of Open Source I have included the link below to download the Fusion 360 file, to easily and simply edit, incase the clearances are slightly off. After all, every wood board is different.
-Fully parametrically designed for easy adjustment of clearances using the source files, which can be downloaded using this link. I've also included the source Fusion 360 file on MyMiniFactory.
-Designed to press fit onto a 1x2in (approx 18mm X 38mm) board. For easy installation or removal. Use the M3 Screw hole for added support if necessary, but not required.
-Designed to hold both narrow, and wide spools.
-Designed to maximize the clearance behind the spool, to allow for wall mounting, or mounting in front of shelving.
-Designed specifically for FDM 3D printers to minimize print time, and plastic use, while maintaining a very strong part. No supports are necessary to print this, and in my tests, standard PLA is strong enough, however a gloss material like PETG or Nylon would likely have longer wear and tear.
The print shown was printed in Matterhackers Build series PLA, 210/65, 0.2mm Layer Height.
