I've saw the model that @ChuckTheSquirrel created, however, wifey wanted a middle sized row. So I've made one myself from scratch, following the initial layout, but with a 3d row at 7.5cm instead of 10cm. Took 5 hours and 220g of filament to print on X1C, 0.2 height, 0.4 nozzle, standard settings.

Walls are 1.6mm thick so should hold just fine.
