Tool holder using Onshape sketches and extrusion – 3D design for 3D printing pt2

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.
