Spool-Upcycling for MasterSpool Refills

thingiverse

Human: Remixed [techam's upcycling nut & bolt-system](https://www.thingiverse.com/thing:2782912) to work seamlessly with additional spools. I've kept the original and unmodified bolt intact for clarity. The following spools are compatible with MasterSpool upcycling and **have been thoroughly tested** to work flawlessly with MasterSpool-refills from DAS Filament: * Tiertime/Cetus/UP Fila 700g Spools * Verbatim 1kg Spools Detailed instructions for each individual spool type can be found below. Don't forget to follow these essential steps: * Clean your spools thoroughly after assembly to prevent dust from entering your nozzle. * Secure the inner end of the filament refill while assembling the spool. * Cut the cable ties before printing. I highly recommend using Verbatim spools as a source for MasterSpools. They're easy to work with, feature built-in slots to prevent the two halves from spinning against each other, and the hub can be completely removed for customizations or larger refills like 1kg (1 kg would likely fit without modifications). For smaller 850g refills, one side may need to be trimmed down slightly. Untouched files from the original are prefixed with `original_` and the OpenSCAD-Scripts are included for your own experiments.
