You will need additional hardware for this to work x4 M7x45mm nuts and bolts or longer x12 M7 washers (3 for each corner), x8 skateboard bearings (2 for each corner). Use the washers to space out the bearings as needed. I have noticed the spools are different form each manufacturer. For the table top version you will need to put some anti slip feet on the bottom of the roller. It is also necessary to add the rod supports to stabilize the z axis for all the weight you are adding. You will notice in the pictures I fabricated aluminum L bracket to space the rod support on the extruder side and also put a bowden tube fitting into it to make foe smoother filament flow.
