Filament Winder for my Medium Filament Spool design

thingiverse

Human: Pairs with the spool found at www.thingiverse.com/thing:780874, but could easily adapt to work with other designs, leveraging the hex pattern inherent in the filament spool's makeup. Given limited space for hanging large spools outside my Flashforge Dreamer on my boat, I'll need to do a significant amount of rewinding onto smaller spools - this winder aims to simplify that process. Instructions Print and assemble parts (except for "example.obj"), fitting support pieces together with the axel/spoke pieces until they snap tightly into place. Since orientation is irrelevant, the collapsible design allows for easy storage when not in use. Next, take the vertical supports and snap them into their corresponding holes on the base. The axel crank mount fits onto either side of an axel crank peg; insert a crank peg on one side, then push the other through the spoke and into the hex slot on the axel. This should provide a secure fit but if there's any slack you can apply an adhesive to match your filament material. The spool features male hexagonal connectors on "spoke" that align perfectly with a pair of corresponding hexagonal holes on this spool - www.thingiverse.com/thing:780874 - allowing easy rotation and securing the crank in place. To print without supports or concern about drooping, no part exceeds overhang limits. A low-material-density, light-weight design combines strength from its hexagonal mesh pattern with remarkably efficient use of resources. I made significant changes to the original version. This includes replacing a single long peg that went through everything, to two shorter pegs placed in opposite sides of the axel crank mount - much easier assembly without applying pressure to either handle or main shaft!
