Clamp for an ipad to attach it with an elastic strap to your upper leg, just like a pilot kneeboard. This clamp is a complete redesign of the clamp by Kevintjuh. The attached Blender file contains both the original design by Kevintjuh, a redesigned version to make printing easier, and a parametric version. The parametric version allows to adapt the the thickness of the tablet and the width of the elastic strap. The adaptations require some knowledge of the Blender modifier stack.

Note that the redesigned version is 5 grams heavier than the original version, 14 grams instead of 9 grams per piece. If weight is an issue it would be easy to take away some material between the two extensions that grab the tablet, just adapting the size and positions of one of the cut-outs in the Blender file.
