Repeating Crossbow Build Step By Step
Repeating Crossbow Build Step By Step The basic version consists of 13 elements. The design is optimized for 3D printing with a layer height of 0. 2 mm. 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 2530. I also recommend printing at a slightly higher hotend temperature than usual. I recommend printing on glass bed to make the surfaces smoother. The 3D printer should be well calibrated (extruder steps, flowrate, first layer height). It takes about 4050 hours to print all basic parts (depends on the 3D printer). To build the bow you must have: FDM 3D printer with a heatbed of at least 200 x 200 mm About 0. 5 kg of PLA filament 15 pieces of M3x20 mm Allen screws 15 pieces M3 nuts 2 pieces M3x16 mm screws with flat round head 1 piece M4x40 mm Allen screw 1 piece M4 nut 3 pieces of steel springs with a diameter 8 mm, length 20 mm and wire diameter 0. 8 mm 35cm (2x15 c
