About this 3D model

This is my entry for 3D Printing Nerd's spool holder contest. This design uses very little material while still providing high stiffness. It can hold spools of up to 95 mm width. I printed it with 3 shells, 4 top and bottom layers, no support, 0.2 mm layer height on a 0.4 mm nozzle. This resulted in a material consumption of just under 25 grams.
