When 3d printing holes, they are always smaller than what is designed.

So I made a template with holes from 1mm to 5.9mm (increments of 0.1mm). Useful if you don't have small drill bits.

Example of use:
-If you have a shaft of 1.5mm, let's say an electric motor shaft.
-Insert the shaft into the template, see which holes fit nicely.
-Write down the size according to the template: 1.70mm
-In Fusion 360 or tinkercad, the hole you need to draw is 1.70mm.
