A snap fit assemble crossbow, needs 2 rubber bands.

While V2 was mainly improved for the problem of parts colliding with each other and breaking when shooting, V3 was mainly improved for ease of assembly.
Please refer to the video in the gallery for assembly instructions.

The joint structure of the rail and grip has been changed.
Clearance between some parts has been increased.
Added wall mount holders (stapled version and M4 screw version)
Batch printing can be done with "all.stl". Please print with rafts and with supports.
