In this remix, I closed the vertical slots to increase the rigidity and reduced wall and base thickness to reduce print time. At 0.7mm line width and 0.3mm layers, the print requires 2 perimeters, 3 base layers, and no infill. It has suited me to utilize only a single 200mm tall model and simply set the slicer to stop at desired height.
The hex 'cells' fit together quite snugly, especially if over-extruding, but I prefer it locked together this way - I haven't had any instances of not being able to tap / whack them into place, and it also allows short cells to be installed up off the table surface.
Line width: 0.7mm
Layer Height: 0.3mm
