Revised Friendly Straw
This is a redesign of friendly straw;(https://www.milbat.org.il/en/thisables/friendly-straw/).
This new version is designed to print on its side, so there are no supports, and it is easier to print. This should fit on most small plastic cups. The modified version is slightly deeper and wider to fit on slightly wider cups and sit a little more securely in the cups. It can be scaled in the print settings to fit different size cups
