Reusable Spool

This model turns your disposable cardboard spools into reusable ones!! First get print all the pieces and get all the tools that you will need (see BOM below⬇️). (The reinforcement piece is optional but is recommended) Run a file around the thread to get rid of access filament and stringing. Take your cardboard spool and pull off both sides. Put the aligning tool centered on it. Use the precision-cutter to trace the aligning tool. Then line up the center, cardboard spool, (reinforcement piece), and the screw. Take a flathead screwdriver and screw in all the screws. repeat steps 4-7 for the other side. Take your refill roll line up with the notch. Then take the other side and screw them together. finally, you can put it on your ams or external spool and enjoy!!
