In this assignment you will create a bottom and top plate for the raspberry pi so that you prevent electrical shorts when placing the raspberry onto your desk or metal parts drop onto your desk.
Learning Goal: make measurements and read mechanical specifications and incorporate them into your own design. Practice OnShape and compare to InkScape.

Design and bottom and top plate that can be attached to the Raspberry Pi. Design it so that we can attach the motor controller board and expand with additional boards. Please make sure you position the through holes properly and the screws fit. Stand-offs and screws with M2.5 threads available in the laboratory. M2.5 is a metric screw with a thread diameter of 2.5 mm. Do not create a 3D printed model, I will want you to practice using the laser cutter.

Below are two videos and ppt with examples on how you can achieve the goal. These videos are unedited and deliberately raw, so you can see that your instructor and many other engineers need look steps up because they forgot where exactly the command or function is they need.
Getting going, read the specifications, change the page size so the parts fits on the laser bed, make a drawing with InkScape: Video1. You can skip the later part with InkScape if you want to focus on OnShape.
Do the same with OnShape: Video2
If you want to use Solidworks instead of OnShape you create your dxf file the following way:

Have your files on a flash drive so we can cut it together in the lab.
