Here on the north pole, we need clothed arcs for many plants, if we want them to bear fruits. We’ve made a makeshift arc that has honestly been terrible. A nice task for the mpcnc!
I made them in three parts, with a polygon joint. This because I wanted to use as cheap lumber as possible, especially considering the pricing atm. The dimensions are 22x148mm for the lumber. The width of the arc is 1.4m.
