Currently the model is at 1:1 scale which won't fit most printers (table top dimensions are 392mm x 335 mm). Tolerance are 0.2mm between the parts, so some rework might be necessary if scaled down for printing.
I'm still working on a scaled down version or a parametric one.
For all parts print the leg and side support twice. There's no need to mirror them. Parts were designed for printing them flat on the bed for max strength without the need for supports. To assemble glue them together.
