Sketchup Tutorial LESSON 9: Designing and Printing Box with Movable Hinges

In this lesson we use Sketchup to design a more complex 3D device. This box is not a simple extrusion, because the hinges are extruded along an orthogonal axis. Hence in this lesson we learn how to sketch and extrude in orthogonal planes in the same design. In the end the design worked very well, and we printed it both on the Prusa Mk2 I3 and the Raise3D N2 Plus. Prints were successful on both machine.

Sketchup Tutorial LESSON 8: Think Like a Mechanical Designer

In this lesson we help you to start thinking like a mechanical designer. We go through an example of designing in Sketchup and then building on a 3D printer of a simple mechanical device. For this lesson we will be making a simple case for eye glasses. This example has us think about dimensions and tolerances. We will design to design rules, and then fabricate.

Sketchup Tutorial LESSON 7: Understanding Design Rules Tolerance for Slip and Press Fits

Mechanical Design is a lot more than just drawing. It is about understanding your fabrication infrastructure and design rules. It is also important to understand and be mindful of tolerances when you design. Designing with your fabrication infrastructure in mind will ensure your success. For our case, we are designing for 3D printers. This video covers a simple test structure you can design and build to better understand slip and press fit tolerances.
