I hope to have a more self-sufficient 3D printer that doesn't require a PC for basic tasks. I had already installed OctoPrint on a Raspberry Pi 3B, so I decided to add a touchscreen to it. To create a brand-new enclosure for this device, I wanted to choose a solution that combines flexibility and practicality. Therefore, I redesigned a case based on GobRob's design and paired it with yyh1002's modular installation system - I'm particularly fond of this system and often use it for various other purposes

In order to cover the HDMI interface, GPIO port, and audio interface when not in use, I installed dedicated covers on these interfaces. These covers must be printed using TPU material, which is as flexible and durable as NinjaFlex.

In order to securely fix the Raspberry Pi in the chassis, I added some foam cushioning material. In the future, if necessary, I might also install an internal mounting bracket.

At present, I have prepared several design documents:

Octoprint chassis - a main chassis specially designed for the Raspberry Pi
Octoprint chassis cover
Octoprint chassis cover
Audio cover plate - a dedicated cover plate used to cover the audio interface, which also needs to be printed using TPU material!
GPIO cover — a dedicated cover used to shield the GPIO interface
HDMI cover plate - a dedicated cover plate used to cover the HDMI adapter bridge
