I created the base on Tinkercad by starting with a square. I then made it 1 cm(10 mm) tall and 10 cm by 10 cm. I used hole shapes to make the edges jagged. I made the cracks by using tiny rectangle hole shapes to make little crevices. I created the bat by starting with a square. I then scaled it smaller to a height of .5 mm, a length of 5.5 cm and a width of 5.5 cm. I used hole shapes to create the shape of half of the bat. Finally, I copy and pasted it to create the other side so both sides would be completely symmetrical. For the last step I rotated it to fit onto the base.
