This enclosure is specifically designed for a particular low-voltage, 32mm x 32mm, rear-ported PWM Controller. The corresponding PWM Controller can be found on Amazon, Ebay, Aliexpress, etc. and are similar to the following:

The enclosure model is a simple single-piece, print-in-place box that does not require supports to print. It includes hinges, port/wire lock/dial holes, 20mm rail-mount holes, and can be locked closed only using PWM washer/nut hardware.
Print settings used in example images:
.4mm Nozzle
.16 Layer Height
33 Walls (Some slicers show reduction of print time with high wall count for this model)
- A larger nozzle may be used to reduce print time
- Higher layers may be used to reduce print time; this may affect hinge durability for better or worse.
PWM encoders can be incorporated in to FDM printers - why and how? Fan control! Routing a printer's fan power cables through a PWM encoder allows the user to lower or shut off fan speeds. This can be helpful for troubleshooting, noise reduction, improving hotend preheat speed, enhancing a hotend's ability to reach upper limit temperatures for high-temp prints, or overriding high nozzle fan speed.
