Parameterised DIY polytunnel seedling planter
thingiverse
Redo of https://www.thingiverse.com/thing:4775495 to be parameterised after seedlings started outgrowing the polytunnel after only a couple of days. Set to 4cm arches, edit arch5.scad in OpenSCAD and change to whatever is needed. I suspect arches set to any taller will require arch_thickness to be increased.
