By using the internal rewinder spring. I was able to fit 4 spools in my EZY 18L/19QT. With this configuration, I can replace one spool at a time without having to take two or more out.
Stand_v3.3.3Rev 2_NotFlat - I removed the bulge from the bottom sides of the supports. I cut this model so that I can adjust the distance. I used double-sided foam tape on the bottom to keep them in place.
Stand_v3.3.3Rev 2_Flat- can be used for the ends.
The author remixed this model.
