Submarine Powered By Rubber Bands

thingiverse

This model of a submarine is built with simply four geometric shape components in Tinkercad, using a Square, Sphere, Paraboloid and Tube. Print this model to enjoy, or get inspired to create Snappy Science. Stretched rubber bands are loaded with potential energy! I have included a step-by-step walkthrough instruction on how to create this model. Great for students learning about science and how potential energy works! Print Settings: Printer: Malyan M180 Supports: Yes Resolution: 0.2mm Infill: 20% How I Designed This We'll talk about designing our 3D model of a Submarine in this section. In the next sections, you will learn how to perform drag and drop geometric shapes onto your workspace. How to change dimensions. How to hollow out geometric shapes. You will also learn how to align and group shapes together. Tools: Needle Nose Pliers Material: Jumbo-smooth paperclip, rubber bands. To scale each shape exactly, we use the Ruler tool from the Helper menu on the right side. To hollow out a shape, use the Holes tool from the Helper menu on the right side. To align a shape, click on the Adjust menu at the top menu bar. To group shapes together, click on Group at the top menu bar. Project: Design a Submarine that is powered by potential energy from simple components. A Square, Sphere, Paraboloid and Tube. Print this model to enjoy, or get inspired to create Snappy Science. Stretched rubber bands are loaded with potential energy! I have included a step-by-step walkthrough instruction on how to create this model. Great for students learning about science and how potential energy works! Objectives: • Design and create 3D printed submarine from scratch. • Build complex designs from simple component pieces. • Learn basic 3D design skills and how to use Tinkercad or other modeling software. • Explore science with the use of potential energy. Audience: • Anyone of any age that is new to 3D modeling can use this project to get started with Tinkercad. • Students in grades learning about science and energy. To study how energy is stored and released. • Learning how to construct models that use potential energy. Preparation: • Students need access to computers and a reliable internet connection, and be logged into a free Tinkercad account (either with their own accounts, or each logged into the same classroom account). • Tinkercad is easier to use with a mouse than with a tablet or trackpad, so computer mice are recommended. • No previous 3D design experience is required for students, although familiarity with Tinkercad would be helpful. • The instructor should be comfortable answering modeling questions about Tinkercad and advising students on design features that might cause printing difficulties (overhangs, delicate features, etc). • It's helpful to have students form into working groups of two or three so they can collaborate on the design process. Having students work in groups is also helpful if you have a limited number of computers and/or limited 3D printer access. Classroom Steps & Other Thought Experiments: Step 1: Have each group of students choose a specific part of the submarine to create. Step 2: Have students prepare for creating 3D model parts to print. Step 3: Have the students shape paperclips and assemble models together. Step 4: To test how many windings of rubber band to propel the submarine, set a distance to reach. To study how many rubber bands to use. Step 5: Alternative test is to test buoyancy. Add holes in the model and add weight to the bottom of the model to get it to propel underwater. Step 6: How much more potential energy is needed to move the submarine while underwater. Put your wonderful imagination to work!
