This is a remix of an original found on Thingiverse, (thing:1771629).
The original was great, and has saved my pen from getting broken, however i found it would ofen fall off in my bag, so not doing what it suposed to.
This version has been extended by 30mm to provide a more secure fit on the pen. It still has the cutout for it to attach to the side of the Pro.
Printed with a big brim, 10 turns to make sure it says stuck down, and at 0.16mm layer height.
The author remixed this model.
Extended the length to hold it more securely.
