Cover for a solderless 9 pin D-Sub connector

Cover for a solderless 9 pin D-Sub connector. (see photos)
Prints in two halves, no support required. Finding the right size screw to mechanically join the two halves may be tricky!
At the present time, unless the connector your fitting the assembled unit to has it's own connecting screws, there's no way to screw the D-Sub connector into it's counterpart as there's no access to the screw holes from the rear, so in this case it's push fit only.
Designed to allow access to the crimping screws and the wiring holes without having to unscrew the two halves.
