Tool for Annoying Gift Tube

The Annoying Gift Tube is a fun model, and very well designed. Sometimes, to mix it up, I print the middle tube a different colour than the other two, which can lead to the threads sticking slightly when assembling.  To aid in the first fitting of the parts together, I have created this simple tool which gives a better grip on the recessed lid parts so the parts can be worked against each other a bit to loosen them up.
