Here we have a strap holder that you stick onto a tablet/ebook/flat object. The ergonomic bulge makes it very comfortable to hold in your palm or control with your fingers. If you have ever dropped a tablet or are tired of your hands getting tired from holding a heavy tablet for long periods then this is for you.
This is designed to take any 2"/50mm wide and 3.5mm or thinner strap; I prefer a sewn nylon webbing with velcro/hook&loop to allow adjustment, but simple slide locks can allow any material to work.
Make sure you measure the width of your palm to buy the right size. More importantly make sure the Limpet handler is not bigger (dimensions in picture) than the object it will be taped/glued to or it will look wonky. The Shapeways versatile plastics are extremely strong, nylon based, and my designs have 2mm thick minimum dimensions so this gripper will last a lifetime.
