There are a number of great 3D design and mesh software packages available on the market. We suggest:
Tinkercad - a great place to start learning 3D design
Fusion 360 - from Autodesk, an intermediate package that offers free licenses for hobbyists and startups
Meshmixer - works with existing mesh files or scans to fix problems or add enhancements
Be sure to check on the system requirements for any software you install.
Important: When you save or export files from your design software, be sure that it is using the correct units (millimeters). Software that is used for 3D design sometimes exports in inches or even without units at all - this can cause unexpected results.
