Hole Drilling Mechanism

This will help you collect dust but not only that it also has more holes ranging from .5 to 11 MM. Then it has a ruler ranging from 0 to about 15 CM to help you measure where you want your hole. When you are not using this it is good for putting drill bits in. 

Tips:

• Print without supports with 30% infill.
• If you want letters to show up better print on like .08 .12 .16
• Print how it is shown in the 1st image above.
