I designed a few Grips for the Apple Pencil 2. They might work on the Apple Pencil 1 but I do not have one to test. There are three sizes (Normal, Ergo, Big) and one Normal version with a cut out for the touch sensitive button on the Apple Pencil. I like the Ergo version the most since it is the smallest (thin area for the finger) and the index finger and thumb can be placed nicely.

All versions can be printed in TPU without support material. The bottom of the mount is closed in the .stl file to ensure better bed adhesion. The bottom is one layer thick (0.2mm) and can be cut away.
