Printable "Precision" Measuring Tools

thingiverse

This project is a highly adaptable and engaging lesson plan that can be tailored to various age groups, subjects, and skill levels. It involves creating and using precision tools, such as a fillet gauge, to measure objects, calibrate printers, and create 3D models of real-world objects. Here's a breakdown of the key aspects: **Audience:** * Suitable for any age group, from young children (with adult supervision) to adults. * Can be used in various subjects, including math, science, art, shop/handcrafts, design. **Subjects:** * Math: understanding precision tools, measurement, and accuracy. * Science: exploring the properties of materials, calibration, and testing. * Art: creating 3D models and reproducing real-world objects. * Shop/Handcrafts: learning about precision tools and their applications. * Design: applying mathematical concepts to create accurate 3D models. **Skills Learned (Standards):** * Understanding what precision tools are and how to use them. * Measuring objects using various tools. * Calibrating printers for accurate prints. * Creating 3D models of real-world objects using CAD software. * Comparing the accuracy of printed models with real-world objects. **Lesson/Activity:** * Can be scaled from a simple show-and-tell to a more comprehensive project involving printer calibration and 3D modeling. * Involves printing precision tools, measuring objects, and creating 3D models. * Can be done individually or in groups, depending on resources and class size. **Duration:** * Can be as short as a single class period (passing around an example tool) or as long as multiple days/weeks for a more comprehensive project. **Preparation:** * No prep required for simple show-and-tell. * Requires a printer, internet connection, and filament for printing precision tools. * May require additional resources for larger projects, such as CAD software and 3D modeling experience. **References:** * N/A **Rubric & Assessment:** * For show-and-tell: pass an object around and have students measure it with various tools; grade based on accuracy. * For full-scale project: grade based on tolerance (+/-) between reproduced real-world object and printed model. **Handouts & Assets:** * N/A This lesson plan is a great way to engage students in hands-on learning, developing their skills in measurement, calibration, and 3D modeling. It's adaptable to various age groups and subjects, making it an excellent resource for teachers looking to incorporate precision tools into their curriculum.
