These models will allows you to use any left over keyboard switches and turn them in to a fidget! You can choose any size from 3, 4, or 9 switches for the right amount of keys you have to customize your toy. I personally enjoy 4 with click switches for the clicking sensation. 

All you need is spare key caps and switches of you choice

Note: Most of the models are NOT it the correct orientation and will need to be rotated in the slicer.
