I decided to build two cranks for my homework, crank a and b. The hardest part like for my cranks was the cutting and using the knife. The folding part also took a while, but the assembling was fun. I enjoy assembling and making things, so I enjoyed making the automata. I messed up on the glueing for the first crank, so I had to rip it apart, and realized I was going to have to reprint it. The first one was also easier, because there were video instructions, and on the second crank, I sometimes got confused with the instructions, but it all ended up well. Overall I enjoyed the automata and think these were really enjoyable.
