Notes:
Cura5.0 above is the recommended slicer for this model. Rafts and Supports are generally better in Cura.
The 3mf files were generated with Cura Slicer. STLs also provided for other slicers.
The body requires tree supports when using "touch build plate only" support option. Please check the print preview before printing. It is better to print the two parts separately.
