Double-neck dosing/dispensing bottle

• Bottle neck and cap are made with Steve DeGroof parametric cap/lid https://www.printables.com/model/216019-parametric-bottle-cap-jar-lid

 While the cap of the ‘big’ chamber is screwed on and the one of the small dosing chamber isn't, squeezing the bottle will increase the pressure inside pushing the liquid through the small tube on the side to the small chamber on top. Ideal for detergents or other liquids that require frequent but not extremely precise small doses. Personally I use it for the fabric softener, it should work with any liquid that's not severely viscous.

Printable without supports in the upright position, I suggest using transparent TPU for this bottle and since it takes about 218 grams of it, please make sure you can produce watertight prints with some small tests before printing this one.

• 2,5mm retraction
