thingiverse

This a box with hidden hinges. The box shape is make with octave. It is a hyperellipse (basically a rectangular prism with rounded edges) inverted on a sphere (https://en.wikipedia.org/wiki/Inversion_in_a_sphere) to make it less boring. The hinges are based on hidden_hinge Thingiverse # 2401035 This is set up to use sections of 1.75 mm filament for hinge pins. Since both filament diameter and printer performance vary, it would be a good idea to make the test strip "hinge_hole_size_test.stl" first, and see what size hole works best with your printer and filament. you can ream out the holes easily by using the side of a small drill bit (like 1/16" or 1mm) to improve the fit of the filament hinge pins. To make, print the following (where xxx is the hole size determined with hinge_hole_size_test.stl): quan 1: blob34_1_bottom_xxx.stl quan 1: blob34_1_top_xxx.stl quan 2: blob34_1_arm_combo_xxx.stl
