Well, as I got a 3D printer at Christmas I thought I would print one out for my display.
The result wasn't too bad. I think the bezel had been designed with some fancy curves on the front edges and because I printed it face down they had quite pronounced bits of filament that had to be removed, I think I will modify the bezel in Tinkercad to make the face flat.
I tried to sand the face a little smoother but the PLA became slightly discoloured from the glasspaper I used.
The rear was quite good with some strengthening ribs included and I found some small screws that made a tight fit and held in the display.
Next step is to make a backing box for the bezel to fit into but I'm waiting until I finalise the design of the project so I know what depth I need in the case.
I got a quote from Shapeways 3D printing service to print this design and it was £7.65 plus postage, although the quality would be better than from my printer I'm quite happy with the quality and I suppose I could also paint it to get a better finish, I'd better google "painting PLA".

Hi, do you have a link to download the 3D plan for this bracket?
HI Jaro, Wow this was quite some time ago, I will have a look but I'm not sure I will be able to find it, I'm not even sure what I designed it in!
I remembered, the model was downloaded from the Nextion website https://nextion.tech/nextion-editor/#_section4
For anyone adapting this bezel, it helps to treat the rear display-mounting plane as the datum when flattening the curved front. Removing material only from the front preserves the opening and mounting-hole spacing; scaling the whole bezel to improve the finish would also change those fits.
Before adding the backing box, check the connector with its plug fitted, cable bend space, and screw-tip clearance, not just the PCB thickness. A small corner test print containing the front lip and one screw boss can check the seating fit in the intended print orientation without printing the complete enclosure. It will not establish the strength of the finished case.
If you redraw the enclosure in solid CAD, keep the native model and check the exported STEP separately: the local seating depth and hole spacing matter more than the overall bounding dimensions. I work on CADProps; our STEP measurement checklist explains that distinction. The same checks can be made in desktop CAD. CADProps processes uploaded files on its servers, so use only models you are permitted to upload.
