Battery cage for Snapper 7

thingiverse

After the last flight with my Snapper 7, I realized that my solution using velcro on 3M Scotch tape was not very effective. My battery ejected in mid-air. So, I designed a cage for my Snapper's battery in SolidWorks. I envisioned the attachment point of the rubber band and bolt holes at the bottom to prevent the cage from moving due to vibrations. The result is quite impressive, as replacing the battery now occurs faster and it's more protected during crashes. Printing takes about 20 minutes, requiring supports for optimal results. You can print it with PLA, but ABS or flexible materials also work well. I've tested this design on my Snapper 7, and I think it's suitable for the Snapper 6 as well. I've included the SolidWorks file so you can enjoy creating your own battery cage. Update: On July 3, 2018, I added some reinforcements to enhance the design. Then, on July 4, 2018, I took new photos. Some DVR footage of this design in action is available here: https://www.youtube.com/watch?v=o-IRkTWKqls https://www.youtube.com/watch?v=IiSJ_ZppI88 https://www.youtube.com/watch?v=oqbXZsg3BAs
