Pen topper insert for Mini Octopus

Note: This is not the file for the mini octopus. This is only for the insert for the pen., A link is provided for the octopus model.

Someone at work asked if the Cute Mini Octopus could be put on a pen to shake around as you write.

I wasn't sure so I designed one up made for TPU.
