Portsdown 4 enclosure options?

Post by G4GHD » Mon Oct 20, 2025 10:50 am

I've recently built a Portsdown 4 and am using the 7" screen as mentioned by Gareth G4XAT on page 24 of CQ-TV 289.
Unfortunately this screen has different mounting point spacings from the official Pi 7" touchscreen, which would appear to rule out the SmartiPi Touch 2 Case, which has been mentioned on the forum previously. Any other suggestions? FWIW, the screen's horizontal mounting holes are spaced approx. 155mm apart, while the vertical spacing is about 93mm.

I would suggest a 3D printed case. I have been working on a design with Colin, G4KLB. We can send you the STL files.

Mounting the screen is easy, it just requires two brackets making, one for either side to fit to the case. You can either 3D print something or just bend a sheet of aluminium.

Thanks Mike, looks good, but regrettably I don't have a 3D printer myself.

How about one of these, but mounted on its back, ie standing upright?

or something like this?

I googled "console instrument case" which throws up several options.
