A nice, slim housing für Nextion 4.3 displays

When developing this design, I placed great importance on ensuring there were no large gaps between the display and the housing, and that the housing fits as tightly as possible against the housing.

The basic parts are, of course, the front and back.

In the back, you can insert a part for an M6 nut, or simply close the back with a smooth cover.

Two additional parts are used to thread the original display cable. After the cables are pulled back inside, the DuPont connectors lie exactly next to each other, forming a kind of connector tray into which you can then dock from the outside using DuPont connectors.

The housing has a slot into which you can easily insert the SD card, and on the bottom there is also a recess into which you can insert a standard USB port for external use.

The parts that click into the back can be secured with a dab of adhesive... the cover is screwed
