Motivation

Two years ago I bought four 7inch HDMI LCD 1024×800 pixel screens to equip my 3D printers with. My self-made 3D printers were each extended by a Raspberry Pi with OctoPrint. I can only recommend this! It is a great thing to control the printer with OctoPrint in a network!

In my opinion, you should not skimp on a good touch screen to control the printer. I always had the desire to design a nice housing for my rather sloppily installed monitors.

How to find a good design?

In the beginning, you always ask yourself the questions: What should the housing look like and what functions should it fulfill? That’s why I’ve been thinking about my requirements.

The monitor should be able to stand on a table and still offer a comfortable viewing and operating angle. The connections should be concealed as far as possible. Being able to screw on a Raspberry Pi is also practical.

It is important that the design is printable and fits into my printer! So when creating 3D printed parts, I always make sure not to design too many overhangs to minimize the need for support material. I also pay special attention to the stability of the housing to ensure a protective encasement of the electronics.

The VESA75 shot was rather coincidental since a Raspberry Pi case downloaded from Thingeverse contained these dimensions for mounting. Now there are four fold-out feet on the backside which provide a stable stand in different positions! The connectors are protected with a non-removable cap and unfortunately have the disadvantage that a 90 ° angle plug is needed for the HDMI connection.
