This software is low key the best open source CAD software. Although it looks ancient, it's under active development and has a much lower learning curve than FreeCAD IMHO. It's a really good fit for the skill level of someone who has a 3D printer. I've designed dozens of parts for my printer and random crap around the house with Solvespace. It's a very useful tool.

Version 3.1 allows you to use the link feature to bring in STL files. The 3D printing crowd should love it.

Just guaranteed me to look at it!
