Sonoff 4CH Pro R2 enclosure

thingiverse

I am building an enclosure for a Sonoff 4CH Pro R2, which leaves some space below it for wires or screw terminal blocks. The walls of this enclosure are 3mm thick. To close the lid, I used m3 brass insert nuts from Aliexpress and attached them with m3 screw bolts. For cable management, I installed five PG9 cable glands. I designed this case using a schematic for controlling blinds from Lamiacasaelettrica.com and printed it on my P3Steel 3D printer. The holes were printed with support, but I'm unsure if that was necessary. The case fits perfectly after printing, without any adjustments made to accommodate my specific printer model. If you encounter issues with the fit, please don't blame me for not optimizing it for your printer. Printing the entire setup on my P3Steel 3D printer takes approximately 13 hours at a 20% fill rate, which includes about 2.5 hours for printing the lid.
