Predator Spear Retractable 3D print model

This is my first attempt at trying to build a spring loaded prop. as it stands only the middle sections are retractable. you will need to insert a couple of small springs on the half moon pieces to make the buttons function and then make a custom spring to sit inside the detailed grip bar, which when the buttons pressed will force the section to its fullest. i have not printed this yet to test and will continue to develop the outer pieces to also be spring loaded when i have the time. alternatively you can have the piece constantly at full length.

you will need to duplicate the obj to make the other side

    Any update as to whether the design is functional or not?
