Simple tool to use when tying balloons. This is one medium sized. Scale up 15% if you are a person with large hands and scale down 15 % if you have small hands. This size size should fit most.

I printed in PLA but it would be better in PETG for strength.

To use- Insert 3 fingers of non dominate hand into tool.Wrap the inflated balloon tip around the arm of the tool one time then tuck the balloon tip under from back to front. Tada!
