I have a Dell Venue 7840 that runs Fully Kiosk and will be mounted to the wall. I like the idea of a recessed mount so it’s flush with the wall.
Given this is an old model (and not sold in high volumes) there are no mounts on the market so I would need a custom mount.
Have any of you been in this situation and what did you do?
3d printing 
Easier said then done. But then again, home automation is more about the journey then the outcome.
Might give Tinkercad a go and send the outcome for printing
If you go to thingiverse you may find something you can adapt, rather than starting from scratch.
People also use photo frames or other wood/aluminium frames
Didn’t know about thingiverse. Some interesting stuff there. Big thing for me is the flush mount but that shouldn’t be too much of an issue.
Good thing in my case I actually bought a frame with the tablet with a keyboard. So I have the key dimensions already.
My first 3D printing project. Bring it on!
