LM2596 and XL4005 buck converter case

2026/03 Update:

• Resize holes so screws can fit and grip better
• Added new model for XL4005 and other variants. It's 1mm longer and have different board screw position.

I really liked TeoMat's case, but I think the bottom base is thicker than needed since it need that space to heat set hex nuts. These case don't endure that much physical stress, so I removed it.

Change list:

• Shaved 3.5 mm off the bottom removing space for 2 hex nuts. Board can be fixed in place just fine with metal screw biting into the plastic.
• Now print perfectly without support. (original design needed support for screw holes)
• Bigger trimpot hole
• Make the screw cap holes in the top piece larger so it fit my button-head screws.
• Lower stand-offs to better secure PCB in the case
