Description
Tried the original model but realized I wanted more options for height. So I made a version that has slots to support different height riser feet. I provided four options. The lowest should be pretty close to the original. It goes roughly from 5, 10, 12.5 and 15mm. I could probably go even further if requested. I might do it just for fun.
Use 4-6 Walls for the clips. I suggest 20% infill for the clips and the risers. Use TPU for the feet. No supports required.
DO NOT CLOSE THE KEYBOARD WITH CLIPS INSTALLED! You can tilt it down a little bit  and you can always tilt it all the way back with this design, no matter the height of the riser feet used.
The risers are keyed so the left side only goes on the left and right only on the right. The last few mm of sliding the riser into the slot is tough to push past but this is to keep the feet in place. Just press a bit harder to go all the way in and it requires a bit of a push to get them out. After the first couple times it should get slightly easier but once you settle on your desired height you likely won't change them often. If its too tough you can take a file or some sandpaper to the tiny bumps in the front of the slots of the clips. The slot fitment in general might be a little tight. If it's too tight for your printer maybe some horizontal expansion when printer risers would help. Or you can ask and I can try to make a looser version of the risers to fit. Let me know.
Each riser is angled at the bottom to fit the angle of the keyboard so it will lie flat on the surface, with our without the TPU feet. You can use the risers perfectly fine without the TPU feet, but with them you get a bit more purchase on smoother surfaces. The TPU feet extend just a tiny bit past the base plastic. They push right into the risers and will not come out. No glue required.
In order to make these risers work right you must install the Riser clips at the very back of the keyboard. To ensure this I put a backstop inside the clips so you have to move to the very back to slide them all the way on. See the 3D model image to see the backstop in blue. By placing the feet at the very back even when the iPad is tilted all the way back it doesn't overbalance the keyboard and fall backwards even when touched firmly with you fingers.
I wonder if I can build some sort of tilt stop in to stop you from closing without damaging the screen, but it will make the clips look a bit ugly if its on there. Maybe i can look into a design that the keyboard just sits in, nothing on top of the keyboard so there is no danger to the screen, but it will be something bigger to print and carry around…
