I enjoyed working with tinkercad. I’ve had friends who have 3D printed before, but I never actually did it myself and thought it would be much more difficult. I liked using this program because it was simple and made it feel as though it was a 3D space. I had some difficulties with undercuts on my lid and realized i should have printed it upside down for it to have worked better, however it still works and fits inside my cat. It came out how I expected it too, even the size was how I wanted it, I would take a ruler and measure the sizes I set to make sure it was ideal before I printed it.
