Battery Holder

thingiverse

This is a custom battery holder designed for 3 double A batteries, serving as a test case to validate its dimensions for future use in robotics projects. The design utilizes Keystone Electronics parts (5221, 5212, 5222), which are readily available on mouser.com and other online platforms. To assemble the device, simply print it out and then solder wires to the 5221 and 5222 components. Once assembled, snap the 5212s into position within the larger slots, while securing the 5221/5222 parts in their designated smaller slots. Ensure that a spring is positioned opposite each button for optimal functionality. In this particular iteration, the wire holes may be slightly undersized; as such, it's recommended to use them as a pilot guide when drilling to accommodate the desired wire size. How I Created This Design I obtained data sheets for AA batteries and battery terminals, which served as my starting point. Using Solidworks, I generated solid models that would eventually form the basis of this design. Through a series of experimental prints and adjustments to the parameters, I was able to refine the model until it accurately represented the desired dimensions. Once satisfied with the results, I exported the model as an STL file and printed it using my flashforge creator pro with black abs thread.
