This is a mini-figure scale recurve bow.

Important: This bow is scaled so that the handle is 3.3mm wide. The hand of a mini-figure is only 3mm wide. The reason I made it larger is that my printer (a Creality Ender 3 Pro) and other printers tend to print a bit smaller than the actual size. At 3.3 mm, it prints exactly 3mm for me. You may need to scale it differently for your printer.
