Robox 1Kg Spool (Rev.2)

Spool for Robox which can hold 1Kg of filament.

This is a full size spool and designed to print by Robox. u need to print 3 wings for each
side (6 in total). It's thicker than the original in order to hold 1kg of filament.

Use M3x6 (15pcs.) countersink screw, only put 2 screws on each wing and leave the
middle hole open for fixing filament end when winding. Use M4x10 countersink screw to fix the handle of the crank. If u want to use the crank, use M3x8 screws on the outer wings so the spool will spin with the crank.

Memory chip PCB can be installed and just program it with AutoMaker.
