According to the Statement of Vision on his blog, application developer Gavilan Steinman aims to "bring the freedoms that I have found in software engineering to my electrical and mechanical engineering worlds."
Among other electrical and mechanical engineering projects he's explored, he has also created a semi-automatic rubber band gun design assembly using six separate 3D printed components.
"Designing a printable rubber band gun has always been on my bucket list," he says on his blog. "I used the holiday season as an excuse to finally do it. You have to fight consumerism somehow, right? And what better way to fight it than to print rubber band guns for your relatives."
While he originally developed the firing mechanism for the gun in 2009, it wasn't until a few years later that he was actually able to implement the mechanism into a final 3D printable rubber band gun design.
The final design shoots up to six #32 rubber bands (chosen for their low cost and wide availability) and is able to be easily loaded with the six rubber bands thanks to the large holding notches of the firing mechanism's design. For added stability, Gavlin printed the center component of the gun at 100 % fill while the outer parts (orange) are printed at 30% with a honeycomb fill.
Of course, any great 3D printed project that is open source such as Gavlin's is sure to bring in some more contributor who want to improve upon the design. One of these designs, which was created by Thingiverse user nigeljohnson73, improves upon Gavlin's original design for those who may want to omit the screws and nuts altogether.
For "Rubber band gun - no screws required", nigeljohnson73 was inspired by the simplicity of Gavlin's design but chose to make some personal modifications:
"I loved the simplicity of the original rubber band gun by @gavilan, but the need for screws, bolts washers, and no idea what size elastic band to use was a bit of a downer," he said. "So I built this with the innards."
The design also features a shorter barrel that uses size 10 rubber bands compared to Gavlin's size 32.
For those interested in 3D printing their own version of the gun as Gavlin designed it, or to improve upon such as nigeljohnson73, Gavlin has generously released all of his project files for free on GitHub and Thingiverse.
