Masterspool for small printbeds

thingiverse

The filament refill spool breaks down into manageable parts that fit a wide range of 3D printers, including my Kossel Mini model. Print sixteen panels, two rings, and one core unit before proceeding with assembly. Check your XY calibration in the slicer software and perform a test fit using two panels and one ring to ensure they lock firmly together without requiring force. Once you've printed the entire batch, assemble eight panels into each of the two rings. Next, place one completed ring onto the core unit and secure it with eight M3 screws. Then, add the refill material and attach the second ring to the core, finishing the assembly process.
