Desk top cannon

thingiverse

This is a fully functional desk toy, designed to sit atop any work surface. To activate it, simply load a small sphere into its business end, retract the spring-loaded plunger situated at the rear, and then release it with a swift motion. The cannon's firing mechanism, comprising of the plunger itself, can be removed for modification or upgrading by unscrewing the threaded joint that holds it in place. A simple spring from a common ballpoint pen will suffice to enhance its performance. This creation originated from my computer-aided design session using tinkercad, and I have decided to release it into the public domain for others to experiment with and build upon. Instructions: This fully functional desk toy is complete in its current state, comprised of all necessary printable parts. Instead of printing it whole, I prefer to break it down into individual components, allowing for greater ease in assembly. This particular model incorporates my custom-designed ball joint hinge as an integral part of the construction process. It is unclear whether this hinge design came first or was influenced by subsequent creations like the pillbox, but they all seem interconnected now.
