Customized the original Clip Stand for my Kindle Oasis, but not begin symmetrically weighted it rocked sideways when hitting the page turn buttons. As a fix for the rocking, I split the arc in the middle and then added a straight section between the halves.

This model is still customized the same as for the original:  specify the length, height, curvature, etc. To add the straight section, set ‘_stabilize = true’ in the customizer.
