This is a PID control box designed for the Rex-C100 model, specifically for use with an e-nail XLR heater (if you're familiar with ball vapes).

The box features an XLR plug, an AC plug, and an SSR mount located under the PID controller.

For assembly, you’ll need brass inserts, as the holes are designed at 4.2mm to fit 5mm brass inserts (M5 screws might also work, but haven't been tested yet).

This model can be printed with PLA or PETG for added strength.
