LM2596 and XL4005 buck converter - slimmer

2026/03 update:

• Added new models for XL4005 and other variants. It's 1mm longer and have different board screw position.

2024/12 update:

Added a new v2024.12 with these changes:

• Even slimmer (-1.5mm)

• Now print perfectly without support. (old version needed support for screw holes)

• Bigger trimpot hole

• Lower stand-offs to better secure PCB in the case

=====

I really liked Teo84'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:

• Move bottom half's circuit board holes to fit my board's position

• Shaved 2mm off the bottom removing space for 2 hex nuts. Board can be fixed in place just fine with metal screw biting into the plastic.

• Enlarge holes in the top caps to fit the variable resistor easier

• Make the nut holes in the cap larger so it fit my button-head screws.
