It'll require a strong hand/glass, but you'll catch all of it.

Easy to clean, just rinse it with some water.
Made with Ultimaker PLA, so it's hard but not suitable for the dishwasher.
I've included the Skechup (version 8) file so you can amend it to fit your glass or cup.

How to use:
- Mount it on the rim of your glass.
- Cut a lime/lemon in half.
- Push and squeeze the lime/lemon slowly down on it, rotating helps.
- BEFORE removing it, fill the glass with soda water by pouring the fluids over it.
- Remove & drink.
