Predator Spear Retractable 3D print model

This is my initial stab at constructing a spring-loaded device, and as it currently stands, only the central segments are retractable. To get the buttons functioning properly, I'll need to add a few small springs to the half-moon sections, after which I'll have to create a custom spring that fits inside the detailed grip bar. This custom spring should be designed so that when the buttons are pressed, it will push the section fully extended. Unfortunately, I haven't printed this yet, so further testing is required. Once I've had the chance, I plan on developing the outer components as well to see if they can also be made spring-loaded. If time permits, it's also an option to keep the piece at full length constantly instead of retractable.
