File: Lobe Set.STL Name: Lobe Set Material: 29.69 grams (0.065 lbs) Size: 109.19mm (4.3") x 64 mm (2.52") x 31.75mm (1.25") Resolution: 0.20mm Layers: 260 layers Print Time: 3 hr 2 min Function: Set of three parts - a "caliper" tool with two parallel sides and a hole - a "perfectly round" part that slides between the parallel sides and into the hole - a three lobed "kind of round" part that slides between the parallel sides but will not go into the hole. This shows the classic GD&T issue with measuring roundness with two edges that is terribly flawed.
