iPad pencil holder for magic keyboard

I have an iPad and an apple pencil. I love the combo but with the Magic Keyboard case the pencil is only held in place by a couple magnets. An accidental tap and the pencil is lost forever. This is a simple holder that sits between the iPad and case to hold the pencil in place. 

It prints vertically, I‘ve found a brim helps with materials that don’t have great bed adhesion.
