Lasercut bottle holder for drying

thingiverse

I'm using this bottle holder for my 0.5L water bottle at work so it can dry properly. The opening for the bottle is 4cm in diameter, which makes it likely to fit most bottles. I built it with 4mm poplar plywood, but any 4mm wood should do the job just fine. Using 3 or 5 mm wood might also work, though it will probably look a bit rough - sandpaper can help smooth out the edges if needed. Assemble this carefully, as you may need to soften the hinge cuts with water.
