mydrill gauge design

This is my drill gauge the steps i had to do is-
1. create a circle cilinder

2. then the measurements to that are 6 in the middle-88 at the bottem side- and 102 and the sides for lengh

3.then you get more cilinders and the height is 6 and then you add 8 cilinders for the drill bits

4.them make them hollow

5. then you can add a text in the middle (Your name- any text you want)
