A 2m cupboard to fit all my tools 'n stuff, made from obsolete nightstands. A bit of rough carpentry and blacksmithing. No electronics.
it is pretty straight forward: take a folding rule, a buzz saw and a jigsaw - and do it. The retractable gear is another thing. When I finish the last parts in CNC I will publish pictures. For now the lift shifts on laser cut
MDF rails and I expect them to break soon. The made to measure rear wood apron took me several (ever shorter) iterations to make the desks fit. No way to get it right the first time as the old furniture isn't straight.
