High Strength Filament Spool Winder

prusaprinters

This is a high strength spool winder for using with standard cordless drills. Very handy for rewinding filament from one spool to another etc. The original was an ideal general shape but required supports and allot of infil. This remix has almost no infill, requires no supports or extra hardware. It has been hollowed out meaning perimeters are thicker where they should be and no infill. But the part that makes it much stronger than usual is that the shaft the drill grips onto is printed separately and horizontally making it it much stronger. it also runs the full length of the threaded section giving it much more strength in tension than vertically printed thread would be. To assemble push the shaft into the back of the screw section (blunt end first) until it is just poking out of the threaded end. Then superglue the hex shaft into the screw from both sides to tie them together structurally. The shaft is 12mm the maximum that will fit in a standard drill, turn it slightly as you push it in as it will have to be in the right rotational position to go in.
