3D Printable Bucket Wheel Excavator

A few weeks ago, I was bored in my middle school's Digital Manufacturing class and wanted to make something different than the assignments we have to do. Later, I saw a bucket wheel excavator and knew it was going to be a challenge. I ended up using most of the skills that I learned about from using Fusion for around a month. Then, 2 weeks ago during the class, my friend found this contest and told me that I should try it. I did some research and ended up finishing the project over our winter break.

1. 3D Printer
2. Filament of any Color
3. Glue
4. String

Glue the Bottom Part of the Arm to the Arm. Make sure that they are around the cylinder of the Main Body.

Glue the drive wheels to the suspension.

Glue the Tower to the main body, make sure it does not fall forwards or backwards.

Line up the sprockets with the drive wheels and glue them onto the rods.

Glue the ovals to the wider part of the pegs. Make sure to keep enough space between them for the sprockets to spin. Put the rectangles on the smaller end of the peg. Continue until you have 2 long chains of equal length. You will need 164 pegs, 164 ovals, and 82 rectangles total.

Link the 2 ends of each chain together. Make sure each of them has all of the sprocket teeth around it.

Put the gear in the hole on the side of the arm. Then, put the wheel turner into the other hole. put the wheel on the wheel turner.

Thread string through the hole on the arm and on the tower on the main body.
