I exclusively use openscad. I can treat a project like software, with git and make.

I started when I had a Smart Car, which made backing in really easy. The front wheels are almost in the same place as the back wheels, so the car almost rotates. It’s a shame they weren’t more popular.

This is why I started. There is a conspiracy of children living in my condo complex, and they ride their bikes in the parking lot. (What’s the collective adjective for children?) I figure I’m more likely to flatten one backing than driving forward, and I’m less likely to have a child behind me when backing in than when backing out. I know it’s a mistake for children to ride in parking lots, but it’s not my choice. They are not my children. My children made their mistakes thirty years ago, and I’m no longer responsible for them.
