OpenBox Printer

Why I made OpenBox

In 2020 I wanted a new 3D Printer. Till then I owned the Anet A8 and I was starting to reach the limits of what the machine could do. ABS prints were hard to print as they would warp, so I had to use a LOT of glue stick to keep prints adhere to the bed. The printer was loud and flimsy being made of laser-cut acrylic; it could only print with a single material and the build volume was merely ok. To top everything off it didn’t even print accurately with prints being a little skewed.

One of the problems was I was still in school so I couldn’t afford an expensive printer like a Prusa i3. And the Ender 3 didn’t have many of the features I was looking for, like multi material, silent stepper drivers and an enclosure to help with ABS prints. If I did buy an Ender 3 I would basically have to rebuild the printer… And then it hit me! If I can’t find the printer I want, I’ll just build one!

I was inspired by the OpenRC project to make my 3D printer open source (The OpenR/C Project – Daniel Norée (danielnoree.com))

NOTE: I’m working on the enclosure now and once that is done ill retake the photos with cleaned up wires!

What the design goals where

When I designed OpenBox I had some design goals the printer needed to meet, these design goals were

Build Goals
  • Parts can be printed within a 220mm x 220mm x 190mm printer
  • Easy to print parts with little to no supports
  • Built around the 20mm T-SLOTTED aluminium extrusion
  • No CNC cutting
  • Off the shelf 3D Printer parts
  • Easy to assemble
Functional Goals
  • Large build volume
  • Silent stepper motor support
  • Dual extrusion
  • Heated bed
  • Enclosure
  • Rigid design
  • Swappable Print head
  • Good print quality
