ESD Grounding Plate

thingiverse

ESD Grounding plate. I really liked this design so I remixed it instead of making my own. Original at: https://www.thingiverse.com/thing:4022034 I increased the hole size to accommodate a standard US green grounding screw, and took out the threads. The grounding screw will self-tap. The grounding screw mount point has also been shored up, I was pretty sure that at some point I would hit the cord and break it off. I couldn't find the exact banana jacks used, so I changed them to use the cheaply available ebay jacks (shown pictured). Remove the outer sleeve and the jacks are a light press fit. Designed so that supports are not required. I also added a strut as I'm guaranteed to bang this at some point. I printed at 35% in ABS and it's very strong. It should survive all but the hardest knocks. Freecad source provided for the remix. Update: Finally installed it. #4 sheet metal screws were too thin, I used what looked like two #6 sheet metal screws. It's solid enough I can shake my whole bench by pulling on the plate.
