A simple replacement handle for most cheap spray bottles.

Split in half in your slicer, or simply print the "Pre Split" Model if you're using the exact same size.

You should sand the contacting edges to help the glue stick better.

You will also need to drill out the holes in the handles to 3.2mm and use a hammer to get the pin through the bottle and the handle as its designed to be a very tight fit.

EDIT 04/02/2023 Changed size of pin to fit a bit better
