SolidWorks initial Model

2D tools: I sketched the initial sketch by using lines and circles, then apply circular pattern to the 16 diameter and 8 diameter circles to make 6 of them around the 62 diameter circle. 3D tools: After completing my first sketch I extruded boss/base of the top circle and 3 bottom circles, then i used sketch and convert entities (2d tool) and trim entities(2d tool) to then extrude the middle body. After extruding everything I started a sketch on the bottom middle circle to make an extruded cut of it. At the end I applied 2mm fillet onto the top circle face and 3 bottom circles' faces. Mass= 60.59 grams Volume = 60591.85 cubic millimeters Surface Area = 26861.88 square millimeters
