Spray bottle holder

The rod is 6mm thick and you can replace it with a longer rod if you want it to hold more bottles.

Print the brackets and attach a rod of the desired length between them. (I personally used a 38 mm long rod which can be found as a file, it fits well for the bottle shown in the picture). Attach the assembled holder to the wall with double-sided tape.

I used PLA for printing, Brim, no supports and 20% triangles as infill.
