Case LM2596 DC-DC buck converter
I developed this case for a motorcycle project and use it in the closed version. However, I only load the module with about 1.7 amps. Alternatively, you can also use the ventilated lid, but in that case, you need to protect the case from moisture. It’s easy to print on any 3D printer and shouldn’t be a big challenge. Even my old Anycubic MEGA SE printed the case without any issues using PETG. For fastening the lid, I used self-tapping M2 screws, and I mounted the module itself inside the case with model-building screws and additionally secured it with a bit of hot glue. Have fun!
