Flush Mount Raspberry Pi 7" Touchscreen

I struggled to find a solution to flush mount the Touchscreen of the RPi without using a 3D Printer, so here is how I made it.

Double sided tape (Tesa tape that has a little cushioning is ideal)

Scrap metal (I used an old DVD burner case)

3mm HSS drill bit + drill

Pliers

4 X 4mm long M3 screws and screw driver

Marking pen

Cutting tool (I used a Dremel)

File

Sharp knife.

The panel will press up against the surface of the enclosure, so I have given some cushioning using some Tesa tape I had lying around from when I replaced the battery in my ph.

Thick double sided tape would also work.

Place the tape on the rear of the screen, all the way around inside edges of the bezel.

This double sided sticky foam will also help hold the screen in place while fixing the brackets from behind, and also prevent dust etc from getting into the enclosure. Don't take the backing off the tape just yet, wait to do a test fit first.

There are 3D printable brackets to do this job on thingiverse, but I don't have a 3D printer so I made my own.

I took the bottom cover off an old DVD burner, and cut a strip off each end. This metal will be used to make U shaped brackets. Use a file to smooth over the jagged edges.

Measure the location of the screw holes for the brackets and use a 3mm drill bit.

Mark a line where to make a bend in the metal that will create enough force to push against the rear of the enclosure. This will hold the screen in place.

Using pliers and the edge of a table, bend the metal along the lines.

The back of the screen is roughly 167 by 101mm, so a hole 170 X 104mm gives you a little wiggle room when you place the screen. You don't have to rely on cutting the hole absolutely perfect as the bezel of the screen will hide any crooked or rough edges.

I used a Dremel to cut through my plastic enclosure and used a sharp knife to tidy up the edges after.

Do a test fit by placing the screen face down on a soft surface (so you don't scratch it) and place the enclose front-side down over the top. Attach the brackets and make sure to use screws that do not go too far through and press against the rear of screen.

Adjust if necessary and that's it, once the test fit is done you are ready to install.

Take off the backing from the tape and tighten the brackets for a flush mount finish.
