I bought the wrong pens for my Cricut Joy so I made this. Adapts pens for the Maker/Explore Air 2 to fit in the Joy.

To use: Put the pen in the adapter so the tip is just sticking out the bottom, and then put it in the Cricut tool holder so the top of this adapter is flush with the top of the tool holder.

EDIT: Updated file to include a depth stop for loading it into the Joy.
