This is my final project, I made it in Tinkercad. It is a combination lock, so it has one dial that controls what numbers you enter, three discs in the back to control what the actual combination is, and a ton of others dials and stuff that I can't really explain. To make this, I first had to look up how to make a combination lock, and because there are many different ways, I had to choose one that could be done with a 3d printer. I then read the instructions on how to make it and what pieces I needed, and made them in Tinkercad.
The final result changed a ton from my original idea, because at first was going to do a tumbler lock, which is a key lock. After looking it up, I realized that I could not do that idea because Tinkercad can not print al of the small pieces, because of how detailed they were. So, I switched t the simpler combination lock.
The hardest part of this project was making sure all the parts were to scale because I had to copy down all the parts I needed, and the measurements were on a different page, so I had to go back and forth over and over again to get it right.
