After looking for an iPad stand that would sit my iPad at 90 degrees and finding nothing, I whipped this up. This is sized specifically for the 2024 iPad Pro 11" M4 and will not fit other versions.

This will stand your iPad up directly vertical and leaves clearance around the screen edges and camera bump so it can be placed in the stand in landscape either direction with no interferance.

To other modellers, I encourage someone to make a remix for the 13" version. I am including the STEP file for an easy start point. I could make a version just going off of Apple's measurements but I have a personal rule of not sharing models I can't test myself beforehand. The STEP file can be downloaded here or you can grab a copy directly in OnShape at https://cad.onshape.com/documents/9a82f60100dd3931f62a452b/w/ffe3d2eab0f9ab14d725f1d3/e/175892a39c652440d33b9017?renderMode=0&uiState=6672d9e0226ed90948fe68fe
