Expanding the lasercut case?

Hey everyone!

I've been looking at building a Tantillus type printer for a little while but I'd like it to have a 200x200mm (100mm in the z is still fine) print bed. I know that Sublime designed expansion panels for the printed version but I've not found any mention on the LC version. So the quesion is can I simply add length (105mm) to the panels and keep all of the printed parts the same to accommodate the larger bed?

Thanks for any info and happy printing.

For the width you can just add half the extra width to each side between the Z axis mount holes and the bearing holes (the bed is not in the center). For depth you may have to design a new Z axis because the cantilever may not be able to handle the extra depth. Height is the easiest and the best to extend. On X and Y the extra size means more wraps of cables on the rods which has its downfalls. But on Z with the cable Z you can go up to 250-300mm without any problems. So my recommendation would be wider and taller. If you must have deeper you may want to look at JimJimma's variant or at least his Z axis which lifts from the side.

Thanks, Sublime, that's exactly what I was looking for and I will keep it in mind. Since this will be my first printer build I will probably save the tinkering and modifying for my next build and stick with the established plans for now.

Slightly unrelated - Has anyone had success/failure using 6mm MDF as a frame material?
And - Would these Self lubricating bearings work in place of all of the lm8uu bearings?
