I printed the shaft holes a couple of mm too big so I will add a bit of sugru later, to make them nice and tight.

the frame

I bought a 2 meter long square tube aluminium profile a the local store of 20x20x1.5mm size. I saw it in 4 pieces of 460mm length so with the 20mm corners that I am currently printing, the size of the frame will be 500x500mm.

I dissasambled the 2 flatbed scanners, which I plan on going to use the sliders and the steppermotors from. I think I will skip the belt drive and go for direct drive threaded rod actuators, because it seems more straight forward and can use less precise (less rotation per step) stepper motors.
