One suggestion for you is adding in some drafting/tolerance lessons. You can end up with a great CAD design that could get undermined with poor prints or tolerances.

The most important thing to remember for design is the design work needs to be communicated, which is done through prints. If you can cnc, laser cut, etc, the solid models are the communication, so tolerance is critical with the CAD models.

Understanding the method of manufacturing also helps with this.
