Official drawing dimensions for the 7" touch screen display?

Tue Feb 02, 2016 1:21 pm

Hi! I've been looking for the official drawing dimensions of the official Raspberry 7" display, but without any success. Does anyone have the official measures for this product? Not only the external ones, but a complete document with all the drawing dimensions.

Please, can anyone help?

Am I the only one not finding the radius of the rounded corner of the lens ?

Hi, I made couple covers. It appears to be radius close to 7 mm, but I just eyeballed it.

Thanks Jakeh12, I made the same measurement but it is comfortable to know you had some concrete successes with it ;)

Many thanks

All the mounting hole dimensions are there, and can be referenced from the edge of the screen and/or the metal back pan. Like many drawings you have to do some math to obtain dimensions not specifically detailed on the drawing.

Example:
The M3.0 holes for mounting the display are 14.95 down from the top of the back pan (21.58 - 6.63 = 14.95) and the mounting holes for the RPi board (M2.5) are 20.8 down from the top of the back pan. So there is a difference of 5.85. Or you could go the other way and work from the edge of the glass. The display mounting holes are 21.58 down from the edge of the glass, the RPi mounting holes are 20.8 + 6.63 = 27.43 from the edge of the glass, giving you the same 5.85 difference between the two.

STL file from spark fun https://cdn.sparkfun.com/3D_Models/prod ... 33/stl.zip
I loaded that stl while rebuilding the screen from the drawing and I noticed that it's bigger than the measurements given, as you can see from the overlap lines in the picture provided; has anyone confirmed that this build is accurate or if the drawing is not?

I have no issues printing it and comparing it to the rpi 7" screen I currently have; but to save time while building I'd prefer not to have to redesign what I'm building in post.

The filet radius I came up with is 6.01211 mm, that is if the stl file listed that I compared it too is accurate which I'm starting to doubt now based on the measurements of my own screen on my retropi console

Image

I measured 110.76mm on my screen which is what I'll use as a confirmation of my template and the official drawings accuracy.

Based on that, the filet radius is based on my measurements and I will confirm this with a quick print is 3.88mm


**EDIT**

I just printed a screen template and the STL provided I believe is designed to deal with shrinkage following a print job, but since I print nearly everything with some variation of Taulman Nylon this will not work; the drawing provided in previous posts is the correct sizing for sure.

Having said that; the corner filet I printed just now fits perfect, the filet radius is 7.017mm

If you use the drawing to build the screen or use it as a reference, the measurements provided should work perfectly.

After I finish building my new console, I'll post the correct to scale screen as an STL so you can use it for future projects.
