Fan-Light Controller V2

To control my 3D printer cabinet extraction fans and lights, I've designed a simple control panel. The control panel functions include: Enclosure light: On/off switch, brightness control knob Webcam Light: On/off switch, brightness control knob Extraction Fan: On/off switch, air flow control knob The control panel sits on top of the cabinet and held in place with double sided (nano magic) tape. I've designed knobs for the potentiometers. The knob 3D print file is available as a separate download. If the host site allows, I've included a design document that details the electrical circuitry, components chosen and photos of the assembly. Parts maybe of interest to others. My print is made in PETG 1.75mm Aurarum black filament, with 0.2mm layer height and 25% infill on a PRUSA I3 MK3S printer. I hope you can find this print useful, too. Remember to leave me some feedback or even a tip to keep me enthused to make more of these drawings.
