iPad Air 5 Adaptor for ESR Ascend 11"

I found the ESR Ascend for iPad Pro 11” M4/M5 for cheaper and higher quality than anything else. But my iPad Air 5 doesn't fit into the inner case supplied. So I had set out capturing the details of the case, including the magnets that attaches it to the keyboard case.

The magnets used are 20x 5x5x2 round magnets and 2x 10x5x2 rectangular magnets. Both of which are widely available. The bottom of the magnet well is 0.2mm from the other side to ensure optimal contact. (I’ve also tried 0.4mm base and the holding strength is suboptimal.) If your printer cannot lay a perfect first layer, you will probably have issues with this design.

Print with supports to ensure the bottom side clamps are neat (there are cutouts for build-plate-based supports to ensure ease of removal. I have also added internal brims to ensure the camera notch's thin edge doesn't curl up mid-print. In the PLA draft, I’ve noticed it is applying pressure to my plastic film screen protector, but in my final copy I intend to use PLA support for a PETG main body, so that should give another 200 microns of working space and a bit of breathing room for the film.

Widest edge is exactly 250mm wide to just barely fit on my printer. I also have my original model that is 1.6mm wider with perfectly rounded corners and better side supports, but that will definitely not print.

If you use a glass screen protector this case adapter will not fit. I have a plastic film screen protector so I haven’t considered that. You can probably remix the file and offset the faces contacting the top of the iPad if that’s a problem.

As of posting, I’m 3 days of normal, portable use into my second full-scale PLA draft print and it seems to be holding up okay. I doubt it’ll survive a heavy fall but at 81g of PLA I’d say it’s expendable. The magnet wells are good fits and they don’t slide out easily, insertion isn’t a pain either. (Face tolerance = 75 microns.)
