2026/03 update:
Resize holes so screws can fit and grip better.
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.
