    I know this is vague sorry, I looking at a box design (2020 + 2040 extrusion) with Ultimaker kinematics.

    This one :- [cdn.thingiverse.com]

    I would replace the top and bottom extrusions with 2040 for added rigidity, I'd probably add a second Z axis as well and use metal to replace plastic were I can.

    Obviously building it bigger isn't that much on a problem BUT I've no idea how big I can go with 2020 and 2040.

    I would value your thoughts.

    Thanks All

    No one can give you an exact answer as it depends on weights and loads.
    How to calculate V-Slot® deflection will be helpful though to calculate if you will have issues, if you know the weights. Checkout the link at the bottom of the page for an excel calculator too
