SodaStream bottle drying rack for two bottles
A rack that holds two upside-down SodaStream bottles so the narrow neck drains and the inside dries, which a dish rack never manages. Each post is 22 mm in diameter and 120 mm tall with three fins that keep the bottle neck open for airflow, and the 1 litre bottle body, about 90 mm across, rests on a 96 mm ring. The base tray is 220 by 110 mm with a 2 mm lip and a rear drain notch so water runs into the sink. Walls are 1.6 mm, the base is 3 mm, and the posts print standing with no supports; the fins prevent a tall post from wobbling.
Bottle dimensions differ between the 1 litre, 0.5 litre and the newer Quick Connect bottles, so a rack generated to your bottles seats them properly. In SpeakCAD you say which bottles you own and how many, preview the rack in the browser for nothing, add a cap holder in the chat and download the STL.
Design a drying rack with a 220 x 110 mm base tray 3 mm thick with a 2 mm lip and a rear drain notch, two 22 mm diameter posts 120 mm tall with three 4 mm fins each, and a 96 mm support ring per post for inverted 1 L SodaStream bottles, 1.6 mm walls throughout.
