Back to Personal Projects

This was one of my earlier projects, and was largely motivated by wanting to test my newly acquired 3D printer. Slingshots had long been one of my interests but I had never been able to make one before, so it seemed like the perfect choice.

I had to work with several constraints, namely print volume and print time. I also did not want to consume too much material, so I experimented with skeletonizing the grip. I drew inspiration from some popular slingshot models I had seen before, as well as some of my own design cues. I ran FEA simulations on the frame to see if it could withstand the forces in theory, and once satisfied I sent it to the printer.

Once finished, I equipped it with a set of latex elastic bands and gave it a try with some steel balls. The frame held up to the maximum pull of the bands with no issues, and fit the hand well. This greatly increased my confidence in the strength of 3D printed materials when designed properly.
