The Logic-Level PC: Giant IRLZ44N Framework Case

The Concept: Power in Disguise In electronics, a logic-level MOSFET like the legendary IRLZ44N acts as a gatekeeper—allowing a tiny 5V signal from a microcontroller to command massive amounts of raw power. This case takes that metaphor literally. To the untrained eye, it’s just a massively scaled-up electronic component sitting on the desk. But hidden inside is a fully functional Framework 12 mainboard. It’s a tribute to the hardware engineering and open-source maker communities: an unassuming disguise housing serious computing power.

Hardware Required:

• 1x Framework 12 Mainboard

• For the Mainboard: 4x M2 Heat-set inserts & 4x M2 Screws (to secure the board to the internal standoffs)

• For the Case: 4x M3 Heat-set inserts (4.2mm outer diameter, ~5-6mm length) & 4x M3 Socket head cap screws

• Drop of cyanoacrylate (superglue) for the bottom pins (optional, depending on friction fit)

Printing Guidelines:

• Front & Back Shells: Print the LogicLevelPC_Front_Shell_Cover.stl face-down on a textured PEI build plate. This will give the flat face and debossed IRLZ44N text an authentic, matte molded-plastic finish right off the FDM build plate.

• Heatsink Tab: Print LogicLevelPC_Heatsink_Tab.stl in a metallic silver or grey silk PLA to mimic industrial stamped metal.

• Pins: Print the three LogicLevelPC_Pin files standing upright. Add a brim if you need extra bed adhesion.

Assembly Instructions:

1. Melt the Inserts: Using a soldering iron, carefully press the four M2 heat-set inserts into the internal mainboard standoffs, and the four M3 heat-set inserts into the outer corner screw bosses on the inside of the Front_Shell_Cover. The modeled 0.5mm chamfers will guide them perfectly straight.

2. Mount the Board: Place the Framework mainboard into the front shell, ensuring the side USB-C ports align precisely with the side cutouts. Secure the board using the four M2 screws.

3. Attach the Heatsink & Pins: Slide the grey Heatsink_Tab into the friction-fit dovetail joint on the bottom shell. Press the three pins into the bottom slots of the front shell (use a small drop of superglue if the friction fit feels loose).

4. Clamp the Case: Place the Front_Shell_Cover over the assembly. Insert the four M3 screws through the counterbored holes in the bottom shell and tighten them into the M3 inserts. The screw heads will sit perfectly flush, leaving the back of your transistor completely flat.

5. Power Up: Plug your USB-C power and peripherals directly into the side cutouts.
