This spray bottle holder is designed to provide quick and convenient access to a small spray bottle right on your toolbox. It securely fits bottles with a diameter of 33 mm or smaller, with about 2 mm of wiggle room when using a 33 mm bottle for easy insertion and removal.

I personally use this holder for isopropyl alcohol, which is a great solution for cleaning a 3D printer’s build plate, but it can be used for any similar spray bottle you want to keep close at hand.

The holder hooks directly onto the brim of the US General Harbor Freight mini toolbox and does not interfere with normal use, as the lid can still fully close while the holder is attached. It’s also easy to remove whenever you need to reposition it or take it off entirely.

I printed mine in PLA, which works well for normal use. While a stronger filament (such as PETG or ABS) may last longer over time, a heavy-duty filament is not required for this part.

Simple, practical, and designed to keep your workspace organized.

Note: As your slicer will warn you, and print with supports
