modular beer bottle drying rack. Needed a drying rack for sanitizing beer bottles for re-bottling in my nano-brewery. 1 or 2 other were available but this design was created to use as little material as possible and increase the evaporative surface. It also needed to be modular for storage and sanitizing. This fits a standard size bottle neck. I've tested that a single unit can prevent a 16oz bottle from falling when it tilts, but doubt it would stop a 22oz by itself. When connected they of course become stronger. The dovetail joints fit tight, with 0.3mm object to object. you could file the sides to loosen it.
