I got fed up with have to constantly squeeze the air from my glue bottle that had been stood upright when not in use. I searched around for something suitable, but none of the designs I found matched the size of my glue bottle.
So I made my own using Fusion 360. Printed with Sunlu PLA+, with 3 perimeters, although 2 would probably suffice, with 15% infill. No supports requited.
The author marked this model as their own original creation.
