Modern Retro Computer Terminals

The goal for this project is to design, 3D-print and assemble the enclosures for several small desktop computers. This series was created during the covid19 pandemic, to get familiar with modern parametric 3D design tools, the limits of 3D printing and fabrication.

A screen size is chosen first, together with the desired components, and then an enclosure is designed around all the constrains (including FDM 3D printing limitations).

All of these have been designed in Autodesk Fusion360 and printed at home on an inexpensive Creality Ender 3.

UltraWide 8.8″ LCD Terminal

Designed around an ultrawide 8.8″ 1920 x 480 LCD, with a rather exotic 4:1 aspect ratio. As this exceeds my 3D printer bed size, I had to figure out a way to split the design in two parts, and how to assemble them effectively. This one is powered by an Nvidia Jetson Nano 2GB, allowing it to run OpenGL natively. Ducky One 2 SF keyboard. Printed on “copper” PLA.

Parametric Models

As building models is quite time consuming, I tried to setup easy ways to explore lots of shapes quickly. After a bit of digging, I found a way to create models in Autodesk Fusion360 by just specifying a few high level parameters.
