A while back, I made a Bic pen with a Flexi Rex attached to it ( https://www.printables.com/model/694375-flexi-rex-pen ), but it wasn't suitable for decorating a pencil. So I created this model to attach to a pencil.

The hole diameter is 7.7mm, designed for a Staedtler pencil. If you want to use it for a smaller pencil, simply thicken it with paper or tape. If your pencil is larger, you'll need to calculate a proportion and print the Flexi Rex at a scale slightly higher than 100%.

If you'd like to make your own Flexi-Rex remix, you might find the STEP file here useful
