ISP built-in socket

Often the controller circuits are built into housings which do not allow easy access to the (hopefully) existing ISP socket. It would be good if this connection were accessible from the outside. In this case it would be advantageous to drill a hole in the housing, i.e. to use a round cutout and not to have to make a square cutout, which leads to the following consideration.

The component is designed for a 30mm drill hole. A standard tub plug can be "clicked in" from behind. In order to be variable, a 6pole variant was created in addition to the 10pole variant. The production in the printer takes about 30 minutes per piece. I printed with 0.4mm nozzle and 0.2mm layer height, material: PLA.

When using connectors with angled connections, Dupont connectors can be used for connection as the connecting wires are longer.
