Case for Electronic Load Battery Capacitor Tester found on eBay

thingiverse

I discovered an easy electronic load and capacitor tester on eBay that's still available from various sellers, making it quite common among DIY enthusiasts. This handy tool caught my attention, so I designed a simple case for it. The design is more of a cover than a full-fledged case, but it works perfectly well for me. The purpose was to create something that can be printed without supports, requiring minimal or no post-print rework. I added holes for 4mm banana plugs (10mm hole) and made sure the design can fit snugly. To print the design, use a low feed rate to avoid making it too tight. It already fits firmly, so this step is crucial. The ideal slicing thickness ranges from 0.15 to 0.2mm when using a 0.35/0.4mm nozzle. Because of some overhanging parts in the design, make sure to use as much fan power as possible during printing. Here's how to assemble the tester: 1) Place the PCB inside. 2) Mount the 4mm jacks (10mm hole is already present) and solder the wires. 3) Plug in the 12V power jack and start using it. Printer Settings: - Printer: K8400 - Rafts: No - Supports: No - Resolution: 0.15mm to 0.2mm - Infill: 15% - Notes: - Use a 0.35 or 0.4mm nozzle. - Full fan speed due to overhanging parts. - PLA works fine, but ABS might result in a too tight enclosure.
