DIY USB-C PD Reflow Hotplate

This is the custom enclosure for my Open Source DIY Reflow Hotplate project. It converts a custom aluminum PCB and an STM32 microcontroller into a portable, professional-grade soldering tool powered by USB-C Power Delivery (100W).

⚠ IMPORTANT PRINTING INSTRUCTIONS

DO NOT USE PLA. Since this device generates temperatures up to 250°C, the radiant heat will melt or deform PLA.

• Material: PETG, ASA, or ABS is required.

• Infill: 20% - 30% (Grid or Gyroid).

• Perimeters: 3 walls recommended for strength.

• Supports: Minimal supports might be needed for the OLED cutout depending on your printer's bridging capabilities.

🔩 Hardware Required (Mechanical)

To assemble this case, you will need:

• M3 Heat-Set Inserts: For the bottom case mounting holes.

• M3 Screws: Various lengths (for mounting the PCB and Heater).

• M3 Nuts: Used as spacers/standoffs between the heater and the plastic case.

• M5 Screws: For bolting the top lid to the bottom case (Industrial look).

🔧 Assembly Tip (Critical)

When mounting the heating plate, ensure there is an air gap between the aluminum PCB and the plastic case. Use M3 nuts or metal standoffs on the screws to lift the plate slightly above the plastic. Do not screw the heater directly flush against the plastic!

Happy Printing & Soldering! If you build this, please post a make!
