Description
This is a remix of the project by @Chris_150569.
The cover is designed to keep the Prusa GPIO Hackerboard, the PC817A Optocoupler Isolation Module, and a Bluetooth remote for timelapse photography neatly organized in one compact unit.
To power the Bluetooth button, I preferred using an external 3V power supply, so I can switch it on only when needed.
The power could also be taken directly from the printer by adding a step-down regulator 5V → 3.3V, but I chose the external supply for simplicity.
The model is easy to print in PLA or PETG and does not require supports.
