Right triangle tracer

thingiverse

My printable shape things are quick to print out with minimal plastic. I designed these designs to be simple and intuitive so that anyone can resize them as needed. Print Settings Printer: CraftBot Rafts: No Supports: No Resolution: optimal Infill: 30% square Notes: I optimized this thing to print in ABS with maximum settings. I recommend a skirt with an offset of 0mm (also known as a brim) with 2-5 loops for ABS. As seen from the photo, increased infill may be helpful. How I Designed This For this project, I used Autodesk's free program TinkerCAD. I'm a long-time user of AutoCAD, a desktop drafting program from the same company. I chose TinkerCAD to make it easier for educators and learners to replicate what I did. TinkerCAD is awesome because it's not only free but also easy to use, with built-in instructional lessons. www.tinkercad.com For this project, I started with the geometric shape 'wedge' on TinkerCAD. To get the triangle shape, I rotated it along an axis. Then, I adjusted the height to 2mm for a strong yet minimal thing. Next, I adjusted it using Shift+click to 120x120mm so that the thing would be large enough to use and fit on various printers, including MakerBots. Then, I used alt+click to create another triangle. I resized it using shift+click to 110mm and moved it to the center of the original triangle. Using hide and group features, I had a final product. Project: Right Triangle Tracer Objective The purpose of this project is for kids to learn shapes by being hands-on. With my tracers, kids can interact with shapes by tracing, cutting, and coloring them. Audience The intended audience is kids 3+ with adult supervision, although these are good for all ages to keep in their craft materials for when they need a perfect geometric shape. Preparation Teachers wanting to modify the size of their triangles will need access to a computer with internet access and a free TinkerCAD 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. Kids should have access to crayons/color pencils and safety scissors, and they must be supervised at all times. Step 1: Adjust size Depending on your project and needs, you may need to adjust the object's size. Download the thing from here and upload it to www.tinkercad.com. Press shift+click on one of the corners to adjust the size. Remember that you can adjust the snap in the bottom right corner for more or less accuracy. Step 2: Print! Check out the beginning of this project for recommended settings. It's good to let the kid(s) in on this process, but remember that there are many hot pieces on a 3D printer. Step 3: Trace Either have your kid(s) hold down the shapes and trace inside or outside them, or alternatively tape the shapes down. Step 4: Cut Assist your kid(s) in cutting out the shapes. Using safety scissors is advised, and using non-straight scissors could add more fun. Step 5: Color If your kid(s) traced inside the thing, they can color it all the way in already. Nonetheless, you can use this part of the project to also teach them about colors. Results The kids can learn about shapes, colors, and scissor safety using this. This will give kids a good head start for their academic careers!
