Cabinet Door Spray Bottle Holder (no holes/adhesive)

Print Settings:

No supports needed (as long as your printer can handle bridges fine.)

Layer height: 0.32mm (you could go lower, but thicker layers will make it stronger)

Walls: minimum 3-5

Infill: doesn't matter; anything >10% should be fine.

Consider printing with a brim due to the thinness of the bracket, especially if your bed adhesion isn't great

Which Model To Choose: 

The standard model is designed to fit standard 19mm (¾") thick cabinet doors (which are also the only type I have to test on.) I included two other models to fit on 22mm (7/8") and 25mm (1") cabinet doors. It also fits spray bottles with triggers up to 30mm wide.

If your spray bottle has a thinner trigger (≤20mm) you can use the “thinTrigger” variant.

If you aren't concerned with how much of the bracket is visible from outside the cabinet, you can use the “LongBracket” variant, which might be sturdier/harder to knock off.  This extends the visible exterior bracket from 5mm tall to 20mm.

Notes:

A small piece of double sided tape or a dab of hot glue may be nice to keep the bracket attached to the cabinet and not fall off when picking up spray bottles; although not necessary. I tested this with every design of trigger-type spray bottle I have in my house, and these dimensions fit every one. Using OrcaSlicer to print the prototypes I once got a floating cantilever warning on one model, but it printed fine and haven't got that warning on any other model, so just a heads up in case you get one.
