This is a modified leg based on ScaryPug's adjustable drawing tablet stand (modular).

I find that the inclined angle of the original version is a bit too steep for me, so I just mod the leg to the height that I wanted. On one of the photo I have shown the angle difference between the original version and my mod version. This is a subjective preference so may not be preferred by others.

Suggest you use the slicer to cut the leg to say 5mm height, print that piece on the printer to see the actual inclined angle before you actually go print the 2 legs - to which you may or may not like the new inclined angle - may save you some filaments which otherwise become waste.

I also increase the height clearance a bit more to clear some other keyboards that I have. In doing so, I made the main arm of the leg a bit thinner.

Important notes:

The legs that are shown on the photos are the earlier version of the legs that I tried - I find that this version gives a bit too much flex (although I dont find this a problem once the ipad is fitted on top of the stand) - but just to stiffen up the thing, I make the main arm a bit thicker. You can see this on the actual stl file enclosed.

I also mod the inserts to the leg as well.
