Oceanic Wave Camshaft

thingiverse

Project Overview: Assemble and Construct a Cam System for an Oceanic Effect Create a mesmerizing oceanic effect by printing out parts in any quantity and fitting together circular cams. This project uses standard pencils, easily obtainable and affordable. Printing parts in multiple colors can create an appealing project. Parts are minimized to fit on the smallest printers. Project Purpose: Educate Students about Engineering and Teamwork This project aims to educate the next generation of engineers through construction and teamwork. Students will learn patience and problem-solving skills by working together to assemble a finished working piece. Print Settings: * Printer: MP200 * Rafts: Doesn't Matter * Supports: Doesn't Matter * Resolution: 0.2mm * Infill: 25% Notes: For the best results, print in a layer height of 0.2mm using ABS plastic or PLA. Sand off any defects for a better final product. Materials: * PLA (Polylactic acid) - biodegradable thermoplastic * ABS (Acrylonitrile butadiene styrene) - thermoplastic polymer Design Process: Utilize free and easy-to-use programs like Tinkercad and Sketchup to create STL files for this project. These programs allow access to general shapes, making it simple for kids to interact with. Project Goals: * Teach students about 3D printing technology * Encourage excitement about new ideas and design concepts * Understand rotational to linear motion and how cams are used Project Name: Sailboats Tackling Rough Seas Overview and Background Information: As a team, you will experience communication skills between peers while completing this project. Concepts of cams and their effect on objects will be explored, as well as understanding keyed objects like the hexagonal pencil. Recommended Audience: Middle school years (6-9), engineering classrooms, or science lessons. Teachers should easily understand and help students if needed. Subjects: * Engineering * Science * Woodworking Skills Learned: * Constructing and modeling in a group * Understanding cam systems and mechanical processes Lesson Plan: * Give marking keys and instruction sheets to students * Rubric criteria for students to follow * Duration: multiple lessons depending on age group or class structure Preparation: No prior knowledge is needed. Time taken will depend on student ability to follow instructions or problem-solving skills.
