Simple spool holder for Mendel or any other reprap printer

Status: fully working.

Description: Its realy simple materiál spool holder. Some parts were taken from my mendel/sinuhed model. Size of threaded rods is increased. This ensures the material position obove 3d printer. Width of holder is twice as big as needed for 300mm spool. This is done to make possible design axis for 600mm spools or universal axis.

Bill of materials

Spool holder

5x M8x300mm
