Clorox ToiletWand is sold without caddy at costco. you can of course buy the caddy somewhere else but when you have a 3d printer, why should you? This model is designed to be printed in spiral/vase mode which I'm a big fan of. Adjust your extrusion width to .62mm even when you have .4mm nozzle. Trust me it works.

Lastly, we want some weight in the bottom so I raised the Bottom layer count to 6 but we could easily throw in some metal bolt/washer if needed.
