I based this model off of the Macintosh Studio model by Scott Yu-Jan. It's a much more slimmed down model, rather than being a full sized Macintosh to house an iPad mini AND a Mac Studio, this is just a front panel to hold an iPad Air. I also added smaller details like the Apple logo in the bottom as well as a floppy disc drive that looks like there's a disc loaded. This model fits an iPad Air 4th Gen perfectly, but you can also download the STL and pop it into something like Tinkercad and resize it to fit other models of iPad.
It includes a stand that slides into the back. I put grooves in the bottom of the stand so you can add command strips that will keep it in place without sliding around. There are two finger holes in the bottom back that you can use to life the iPad out as well as holes for the power button, the speaker and the charge cable.
The project that I have loaded here takes about 8 hours on a P1S. I recommend leaving the supports as they are in the project as there are some steep overhangs in small places. The supports all come out very cleanly though. Enjoy!
