Toy Mini Spring Gun

thingiverse

This Simple Mini Spring Gun Requires Three Essential Components. Firstly, One High-Quality Spring with a Diameter of Approximately 4 to 7 Millimeters is Needed for the Projectile. Secondly, an Additional Spring is Required for the Trigger Mechanism, although this Component is Not Mandatory. Thirdly, a Bolt with a Thread Diameter of Approximately 3.8 Millimeters is Necessary for Secure Assembly. To Assemble the Gun, Insert One End of the Projectile Spring into the Hole and Bend It into Shape. For Enhanced Reliability, We Recommend Printing the Bullet Hook Using the bullet_round2.stl File. If You Desire a Lighter and More Distant-Flying Bullet, Print the Design with 10 Percent Infill and a Shell Thickness of 1 Millimeter.
