Putting it all together
This designed using FreeCAD. I do all my mechanical design using FreeCAD.
I opted for wooden box. I’ll use aluminum tape to have some shielding effect inside. The protector mounted on the top of the transformer. Also, there are two capacitor boards that are mounted on the top of each other.
I plan to add a plexyglass on the front to accommodate connectors and potmeters. Despite the bad look, I’ll have the input in the front panel. So there’ll be no cabling inside the box.
