Electrical plug holder for PCB workstation

prusaprinters

A piece for securing smart plug (European type) in Giuseppe Finizia's PCB Workstation with Nano-Probes. The design requires some creativity in finding a good position. One good position is depicted, but there might be others that are even better. Another solution would be just place a hole 24 mm or more in diameter in the middle of Giuseppe's base piece, then the smart plug can be put squarely in the middle with the prongs protruding below the base.Reason for design: Previously one could reprogram Tuya's ESP8266-based devices (like the depicted Nedis WIFIP110FWT) over the air using the likes of tuya-convert, but recently Tuya has put in the effort to made it difficult. Luckily we have Giuseppe's jig and Vedran's project describing where to connect the wires in order to flash the ESP over UART, and how to flash it using ESPHome :)Printing tips:Print with the flat square side downPrints fine with 0.4 mm nozzle, maybe even 0.6 mm or more (have not tried myself)Use variable layer height in PrusaSlicer (in order to get the screw holes right)Usage tips:Use M3 screws to secure the plug from sides, but don't over-tighten. Two screws should be enough, but there are as many as eight holes, so knock yourself out if you feel like it.It did not make much sense to design threaded holes in this orientation, but the holes' diameter is 2.6 mm, which should make it fairly easy to self-thread with a M3 screw.If the plug is of type F (also known as German type or Schuko), then it might be a good idea to fasten it as shown in the picture, so that the screws push on the springy earthing contacts. You might then even earth it through the screws, if you need to.If you find this model useful, please upload your makes and share your thoughts!
