3D printer must be well calibrated (extruder steps, flowrate, first layer height). For reasons of strength and durability, I recommend printing all elements with a wall thickness of 1.6 mm (4 shells), a thickness of 1.2 mm bottom and top walls, and infill 25-30%. I also recommend printing at a slightly higher hotend temperature than usual. Please read Sliding_Legolini_Bow.pdf file before printing!
