Customizable Supercapacitor Enclosure

thingiverse

This enclosure is designed to house supercapacitor cells or similar battery-shaped objects. Created using OpenSCAD, it remains a work in progress and can be customized and scaled to suit various needs. As my first project, I'm continually working to refine its structure. The lid for this design is available on Thingiverse at http://www.thingiverse.com/thing:1730028. The Git project can be found at https://github.com/jetpack-maniac/Supercapacitor-Enclosure. There's a known issue: screw holes in the center posts sometimes fail to get added to shapes that are longer than they are wide. I'm investigating the cause of this problem. The code is easily modifiable for different component configurations and sizes. The default setup features a 2x3 grid of D cell capacitors. This design was created to support an automotive supercapacitor bank, replacing a lead-acid battery for car charging purposes. Design Philosophy: I aimed to create an enclosure that provides ample space for the cells as well as protection circuits. Additionally, I designed cutaways in the area between the cells to ensure safe and secure storage. The center posts are tapped for mounting various components (in my configuration, I'll be installing over-voltage protection circuits, which I'll post about once complete). The lid features two large bolt holes that will utilize bolts as electrodes to attach the enclosure securely. In contrast to my previous case, where wires were soldered directly to battery lugs and often touched each other, causing issues. This is a prototype, and I plan to print my first two cases this week, making necessary updates based on my experience with them. Stay tuned for further developments, including cap circuits and the final installation and performance of these devices.
