Free-Standing Wide 3D Printer Filament Spool Holder

This is a free-standing spool holder that can hold multiple spools off your printer to keep the weight off and for convenience of switching filaments.

Attach the parts as shown in the photograph with glue or 4xM3 nuts and bolts (12mm/14mm if your printer does not print the recess for the nuts large enough or you can not apply enough compensation). You will need a rod to go between the brackets obviously :)
