A printing arc of a block without support.
The cord measures approximately 20 cm to be able to be manufactured on most 3D printers.
An arrow is provided, you just need to add a rope (I made with kitchen string).
A tip for skewer to have another type of arrow.
A target is also provided.
Installation precautions:You have to tighten the rope a little (it should ring). I advise you to remove the rope after use to keep the elasticity of the materials.
Precaution for use:The boom is projected several meters, it must be used with caution.Do not leave a child unattended by an adult.
have fun
