HyperCube Evolution: HotEnd wiring parts

1) Housing for mounting on a frame made of 30x30 profile, connector DB25
2) Part for mounting cables on the printer carriage.


Design idea
The idea of a cable that does not detach from the carriage at all, but has a connector on the printer frame, I saw here:

I agree with the author: the carriage and extruder is a completely finished block with a certain configuration. It is not necessary to disconnect the cable from it for minor repairs and maintenance of the carriage. It is much more practical to foresee the possibility of easily removing a hotend or fan, or a separate sensor from the carriage. And if there are significant changes, you will need to change the cable itself.


Features of my design
When designing these parts, I set a goal to make them such that the cables, connectors, and fasteners themselves could be separated from the printer without cutting or soldering. Therefore, no detail does not contain closed contours.
