Case for a GPS Breakout in Sketchup (how to make simple cases for your projects)

thingiverse

In the past, I struggled to find tutorials or manuals for making cases for complex projects. For instance, my LCD+touch assembly with three layers of PCBs proved challenging. However, I later discovered that creating a cuboid representation of internal components greatly simplifies case design. Complex projects can be broken down into simple shapes, and the case can be constructed around these forms. If you're interested, you can watch this video (5 minutes long in real time) that demonstrates the process: http://www.youtube.com/watch?v=22wSBw6W1uI. The video showcases a cheap GPS module from eBay called GTPA010, which has two interfaces as described in its datasheet (http://screencast.com/t/teY5OC5N9ry). To create a case for your project, follow these steps: 1) Use a caliper and take notes. 2) Identify the largest components and mentally split them into cuboids. Fewer cuboids are better. 3) Choose a reference point on your object that will touch the case. 4) Ensure external parts like connectors, jacks, and plugs protrude from the internal representation. 5) Screw holes appear as cylinders in your internal model, using the reference point to align all positions with the case. 6) Break down components into at least two sections (internal and shell). In this example, two shells are used. 7) Draw the shell based on the internal model, which is simplified thanks to the cuboid representation. This step is easy! 8) Duplicate your model with the shell components open and make any necessary adjustments. Regularly check the assembled copy to maintain consistency. 9) Print out the case design!
