thingiverse
Adapter for electric water dispenser on 5L bottle. 58mm outer diameter, 38mm outer diameter of threaded bottle neck, 19.7mm diameter of inner adapter hole. Need less than 10gramm plastic Нашёл пару разных моделей аналогичного адаптера, но они все они мне не понравились, сделал свой. Ну и резьба, как я понял, в разный странах (да и в одной тоже) может отличаться.
