The OmniBox Story

The Requirements

Enclosed 3D printing requires controlling more hardware than comes with a typical 3D printer:

  • Lighting
  • Webcam
  • Thermistor (temperature sensor)
  • Temperature-controlled exhaust fan
  • Always-on filtration fan

Isolation From Heat

Most electronics will overheat in the 50C (120F) or higher ambient temperatures of a well-insulated enclosure. I printed my first of Steve Burcham's cases to remove my electronics from such heat; OmniBox is derived from his work.

Flexibility and Accessibility

Devices like fans and lights--and Raspberry Pis!--need a buck converter lower the voltage from a 3D printer's power supply. My cases soon were cramped with bucks. Each one mounted on a tray above the microcontroller unit (MCU); wiring changes to the MCU required that I first remove up to three buck converter trays.

Ample Room

After I discovered BIGTREETECH's Octopus in another project, I wanted a case for it. The Octopus does not fit the cases I had already printed; I also had several ideas to improve upon Steve's case.

With these requirements and goals in mind, I decided to design my own case.

These photos detail some of the evolution of Steve's original case into OmniBox.
