The First stage
The drill model project was chosen and carefully raised using a caliper vernier . An illustrative engineering drawing of half of the device was made and a section of it was taken to illustrate the thickness of the hole.
The Next stage
A prototype of cardboard material was made based on the measurements that were previously uploaded using a vernier for the internal and external parts.
The third stage
After that, foam material was used because it gives more accurate results in curves.
The fourth stage
A layer of putty was applied to the foam model, then sanded and given a layer of paint to finally give us the shape of the original model.
