To get the best out of 3D printing, it helps if you can design your own parts. In this tutorial series, we will learn to use a free 3D CAD program to do just that. In this episode, we model our first object: a simple tool holder for allen keys, screwdrivers, etc. The main tools we use in Onshape to achieve this are 2D sketches and extrusion. There is also a focus on construction lines, constraints, dimensioning, prototyping and exporting for printing. 0:00 Introduction 3D design for 3D printing Onshape playlist: https://www.youtube.com/playlist?list=PLGqRUdq5ULsONnjEEPeBxxStEsobDKAtV Direct link to create a free account: https://www.onshape.com/en/products/free 0:40 What we are designing 1:02 Taking measurements Digital calipers on Amazon : https://amzn.to/3Bu6yjN 1:42 3D printing design considerations 2:04 Creating a new document 2:19 Camera controls 2:53 Creating a sketch 3:50 Drawing lines, rectangles and circles 4:14 Constraints, construction lines and dimensions 8:04 Extrude tool 8:53 Fillets (rounded edges) 9:33 Exporting an STL for fast prototyping 10:20 Adding/subtracting from the model for a mounting boss 13:20 Revisiting 3D printing design considerations 14:04 Conclusion Buy quality and affordable filament from X3D.
