My Shape Designs Can Be Easily Printed With Little Plastic I Made These Simple And Intuitive Design For Anyone To Resize As Needed Quickly Print Settings Printer: CraftBot Rafts: No Supports: No Resolution: Optimum Infill: 30% Square Notes: This design was optimized to be printed 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 in the photo, increased infill may also be helpful How I Designed This Project For this project, I used TinkerCAD a free program from Autodesk I have been using AutoCAD a desktop drafting program from the same company for a long time to make it easier for educators and learners to replicate what I did TinkerCAD is awesome because it's free easy to use runs in your browser and has built-in instructional lessons www.tinkercad.com I started with the geometric shape titled 'star' on TinkerCAD Then, I adjusted the height to 2mm to get a strong but minimal thing Next, I used Shift+click to adjust the size until the long side was approximately 120mm so that the thing would be large enough and fit on various printers including MakerBots Next, I used Alt+click to make another star Then, I resized it using shift+click to 104mm and moved it to the center of the original star Using the hide and group features, I had a final product Project: Shape Tracer Objective The purpose of this project is to help kids learn about shapes by being hands-on Using my tracers kids will be able to interact with shapes by tracing cutting and coloring them Audience The intended audience is kids 3+ with adult supervision although these would be good for all ages to keep in their craft materials for when they need a perfect geometric shape Preparation Teachers wishing to modify the size of their own triangles will need to have access to a computer with internet access and be logged on to a free TinkerCAD account To use Tinkercad, a mouse is recommended over a tablet or trackpad No previous 3D design experience is required for students although familiarity with Tinkercad would be helpful Kids should have access to crayons/color pencils safety scissors and be supervised at all times Step 1: Adjust Size Depending on your project and/or needs, you may need to adjust the size of the object Simply download the thing from here and upload it to www.tinkercad.com Next, press Shift+click on one of the corners to adjust the size Remember that you can adjust the snap in the bottom right corner which will allow you to be more or less accurate Step 2: Print! Check out the beginning of this project for recommended settings It would be good to let the kid(s) in on this process but remember that there are lots of 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 (like those that cut in wavy lines) could add more fun Step 5: Color If you had the kid(s) trace inside of the thing, they could have just colored 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 use this to learn about shapes colors and scissor safety This will give kids a good head start for their academic careers
