Embedded OctoPi Mount - Rostock Max V2

thingiverse

I am excited to continue using my Raspberry Pi and OctoPrint setup, which has been working wonderfully so far. To make it even more convenient, I wanted to design a custom enclosure that would meet several specific requirements. Firstly, the Raspberry Pi needed to be safely housed inside the printer for optimal portability and cleanliness. Secondly, I wanted to have easy access to the power connection and at least one USB port within the printer itself. Having only one power plug on the printer was also crucial, as well as a separate USB port to control the printer board. If I were to upgrade my Pi camera in the future, I wanted to be able to easily install it in the enclosure with minimal cable management issues. To achieve these goals, I decided to use the blank side plate of the base of my printer and design a custom mount that would poke through at an angle. This clever design feature would enable me to cover it up using a right-angle USB cable, meeting all my requirements. Mounting the Pi on this side of the printer provides ample separation from any power couplings or power supply itself, ensuring optimal airflow and reducing heat buildup. Although I may need to enhance ventilation in the base to prevent overheating, this is likely to be addressed in future plans involving a quieter fan installation and targeted ducting for improved cooling. The mount consists of two simple parts: a lower and upper assembly that securely clamp the Raspberry Pi into place, along with the replacement side plate that holds everything together within the printer. The top part of the mount features an open design, allowing for excellent airflow around the Pi. I had some fun adding ventilation views to the mount base by incorporating SeeMeCNC eyes. To secure the mount in place, only two 12mm long M3 bolts are required. Additionally, a USB cable with a sharp right-angle bend is necessary to connect to the printer board. I used a suitable cable from Amazon along with an USB B adapter. As for power wiring, I plan on simply connecting a short extension cord to the external power plug and using the small power block that came with the Pi.
