Magnemite magnet

To make this model you pick a size big, medium or small. You'll need a cylindrical magnet and three bolts, I made a few versions for different bolt/magnet sizes. 

To get the different colors I split the body and the eye into two parts, print the body in gray (or any other color, you are your own free creative little spirit ;P) and print the eye in white. You can easily use paint/permanent markers to color the magnets and dots for the eyes. They are great for painting your prints in general. Another option would be printing the whole thing with a multimaterial system, a few options for those are included as well.

If you are interested in using different sizes, you have a few options: 

-Download the version without the magnet hole and add a negative modifier with the size of your magnet in your slicer.

-I included the fusion 360 file, you can edit the size of the body, bolts and magnet in the “user parameter” tab.

-And step files for the users of other cad programs.

-If you have no experience editing cad files, feel free to ask for a remix for your size of bolt/magnet. Other improvement requests are welcome as well, I would love to make this model better.
