Right Angle Ruler

thingiverse

This is a basic right angle ruler design created by a grade 8 student. The ruler has small bumps at 5mm increments and is designed to help students and teachers in engineering and drawing lessons. Print Settings Printer Brand: Stratasys Printer: uPrint SE Plus Rafts: Doesn't Matter Supports: Doesn't Matter Resolution: 0.2540 How I Designed This This was designed on Autodesk inventor using measurements and 2 simple extrusions and a pattern. Project: Drawing Tool Design Objectives: To design and make a useful drawing tool for teachers and students To make use of the school 3D printer To focus on accuracy in making the tools Audience: Students Grade 8+ in design classes Teachers to potentially use the tools with other students Preparation: Students to survey potential audience and find the most useful products to make, careful measurements must be taken to make sure their product is accurate. A sketch is drawn. Steps: Create a basic L shape on CAD software using sketch and extrude. extrude one 'bump' at the size at the inside corner of the part. Use 3d pattern to copy the bump all the way down the length of the ruler Use mirror at a 45 degree angle from the corner to copy the bumps to the other side of the ruler. Results: The tool printed in around 20 minutes and has been useful, embossed numbers would be a nice addition.
