I like to reuse PET 0.5 l bottles, but getting them to dry completely after washing is a challenge. And if they don't dry completely, they get smelly and disgusting quickly.

This simple drying rack allows up to three bottles to air dry upside down while not blocking the bottle's mouth.

I've done a lot of experimentation with different materials that resist breaking of the stems. PETG, PC and ASA all appeared to be too stiff. The best results were obtained with PLA (in this case, Bambu Basic PLA in white or black). With this material, the stems can be forcibly flexed repeatedly without breaking off (see last photo). Matte PLA did not work as well.

• 2 wall loops
• 25% infill, rectilinear
• Ironing: all top surfaces
