This is a glue bottle holder to store glue bottles upside down. That way you can dispense glue more quickly.

This model was printed in 2 hours in PLA with a 0.6mm nozzle, 0.3mm layer height, and 15% infill. An OpenScad file is included in case you need to adjust the sizes.

The blue rim was a happy accident as I ran out of white filament near the end of the print! But you could do a color change if you want something similar.
