1 year agoA good photo can really go a long way. Back up and zoom in as much as possible to reduce perspective distortion. Try to get the camera square to the part.
Another nice trick for small parts with a flat face is a flatbed document scanner. Unlike a camera, the scanner ensures no perspective distortion. They also have a known scale (the DPI). Or, for more accuracy, you could calibrate the scale factor by scanning a ruler.
Can you explain what you mean by “inside the switchboard”? Maybe a photo?
Normally, you would use standoffs to mount it.
