12 inch nozzle for Seese Jet Blower

My mother-in-law got this handheld blower from Seese.  The link is below.  She likes it but it is so short that there is very little control in blowing.  She wanted to extend the nozzle.  

This is a 12 inch extension for the handheld Seese jet blower.  It is made in TPU with 20% infill.  It is a tight fit and will not come off.  PLA or PETG would probably work, but may not squeeze on without being flexible.
