Summary

Table arms are 117 mm (11.7 cm) apart.
Table top is 235 x 230, 128.8 high.
Print flat, upside down, with the legs up, legs must be supported, I used tree support.

Sofa arm table -final is the whole table with arms attached, print in one piece. Tabletop for sofa is just the table portion, it has cutouts for the supports to be glued to it later. If you choose this option you will need to print 2 "arms for sofa table"
