Carboy Dryer for Plastic 23 litre carboy

I use these plastic carboys from lovebrewing in the UK https://www.lovebrewing.co.uk/23-litre-plastic-carboy/

I've designed this simple 2 piece rack to hold vertically for drying. Stops that annoying puddle forming when they lean.

The rack will suit a neck outer diameter of maximum 58mm. The minimum internal diameter is 45mm.
