Circle tracer

My printable shape thingies can be quickly printed with little plastic. I made these designs simple and intuitive so that anyone can resize them as needed. Print Settings Printer: CraftBot Rafts: No Supports: No Resolution: Optimum Infill: 30% square Notes: I optimized this thing to print in ABS at maximum settings. I recommend a skirt with a 0mm offset (also known as a brim) and 2-5 loops for ABS. As seen from the photo, an increased infill can be helpful too. How I Made This I used a free Autodesk program called Tinkercad to make this project easier for educators and learners to replicate. I've been using AutoCAD for years, but Tinkercad is awesome because it's free and easy to use. It runs in your browser with built-in instructional lessons. www.tinkercad.com For this project, I started with the geometric shape 'tube thin' on Tinkercad. I adjusted the height to 2mm for a strong but minimal thing. Then I resized it using Shift+click to 120x120mm so it would be large enough and fit various printers. With this one, I didn't need to do anything else because the tube is already hollow. Project: Shape Tracer Objective The purpose of this project is for kids to learn shapes by being hands-on. My tracers let kids interact with shapes by tracing, cutting, and coloring them. Audience This is intended for kids 3+ with adult supervision, but it's good for all ages to keep their craft materials handy. Preparation Teachers can modify the size of their triangles by accessing a computer with internet access and logging onto 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, but familiarity with Tinkercad would be helpful. Kids should have access to crayons/color pencils, safety scissors, and adult supervision at all times. Step 1: Resize Depending on your project, you may need to adjust the size of the object. Download it here and upload it to www.tinkercad.com. Then press Shift+click on one corner to resize it. Remember that you can adjust the snap in the bottom right corner for more or less accuracy. Step 2: Print Check out the print settings at the beginning of this project. It's good to let kids participate, but remember that there are hot pieces on a 3D printer. Step 3: Trace Have your kid(s) hold down the shapes and trace inside or outside them, or tape the shapes down. Step 4: Cut Assist your kid(s) in cutting out the shapes. Use safety scissors and non-straight scissors for more fun. Step 5: Color If your kid(s) traced inside the shape, they can color it all the way in already. You can also teach them about colors during this part of the project. Results Kids can use this to learn about shapes, colors, and scissor safety. This will give kids a great head start for their academic careers!
