This is a small part that can be glue to the side of a standard header socket to convert it to an amphenol 5-532956-3 Guide Pin Ear connector for use on a riser card for the HP8647, HP8648 and HP8920 RF signal generators.
By adding this to the side of a female header it ensures that the header correctly aligns into the main PCB when inserted.
Black (to match OEM)
Print at a very small layer height to ensure good detail as this is a very small part.
I printed this OK with a 0.4mm nozzle, but you will get even better results using a smaller one.
