First, we got the original design we created this design in Tinkercad and it was too small for the magnet so we had to create another one.
The Second design did not finish and it ran out of filament so we changed the filament to white.
The Third design was missing the hole and the hole for the pencil was to small.
The Fourth design was skinny and off center that was the correct but the mistakes.
In the fifth project, the hole was too small and a bit wide.
We were finally able to get all the items we wanted and needed in the design.
Inspiration, aka older models, which we use as a blueprint to make our generator. Notice how the sides cave in when the wire was wrapped tightly around it - this is how you increase voltage so it's important. Our design 2 years ago didn't have anything to hold the wire in place and it was further away from the magnet which decreases power.
