Square tracer

thingiverse

My shape things can be printed out very quickly with little plastic. I made these designs simple so anyone could resize them as needed. Print Settings Printer: CraftBot Rafts: No Supports: No Resolution: Optimum Infill: 30% square Notes: I optimized this thing to be printed in ABS with maximum settings. I would recommend a skirt with an offset of 0mm (otherwise known as a brim) with 2-5 loops for ABS. As can be seen from the photo, an increased infill may be helpful as well. How I Designed This I used TinkerCAD to create this project. I have long been a user of AutoCAD which is a desktop drafting program. I chose TinkerCAD because it's free and easy to use. It also runs in your browser and has built-in instructional lessons. www.tinkercad.com For this project, I started with the geometric shape titled 'box' on TinkerCAD. I adjusted the height to 2mm for a strong but 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. Next, I used alt+click to make another shape. Then I re-sized it using shift+click to 110mm and moved it to the center of the original square. Using hide and group features, I had a final product. Project: Square Tracer Objective The purpose of this project is to help kids learn shapes by being hands-on. Audience Kids 3+ with adult supervision are my target audience. Preparation Teachers need access to a computer with internet access and be logged on to a free TinkerCAD account. A mouse is recommended for easier use than a tablet or trackpad. No previous 3D design experience is required, but familiarity with Tinkercad would be helpful. Kids should have crayons/color pencils, safety scissors, and be supervised at all times. Step 1: Adjust Size If needed, adjust the size of the object by downloading it from here and uploading it to www.tinkercad.com. Press shift+click on one corner to adjust the size. You can adjust snap in the bottom right corner for more or less accuracy. Step 2: Print! Check out recommended settings at the beginning of this project. Let kids be a part of this process, but remember that there are hot pieces on a 3D printer. Step 3: Trace Have your kid(s) hold down the shapes and trace in or outside them, or tape the shapes down. Step 4: Cut Assist your kid(s) in cutting out the shapes. Using safety scissors is advised, and non-straight scissors could add more fun. Step 5: Color If kids traced inside the thing, they could have already colored it all the way in. Nonetheless, you can use this part of the project to teach them about colors. Results Kids will learn about shapes, colors, and scissor safety using this project. This will give kids a good head start for their academic careers!
