NEW I made a small but important adjustment to the model adding stoppers which are preventing the unwind of the plastic tubes. The old key can still be used, but the body is having two internal edges that work with the stopper wheels. Print 2 stoppers and the key is getting centered as well within the squeezer ;-).

• Make sure you align the stoppers in the same way!
• Make sure you're rotating it in the correct direction. Otherwise the teeth on the stopper might break and you'll need to print the stopper again (not a very big deal).

I hope you'll like it!

OLD This is another paste squeezer, made from the need of having one that really squeeze ;-) There are a couple of them already to choose from, but this one is using its elastic triangle shape to push and level everything. The SketchUp Maker 2017 file is attached. If you need to change it, make it better, feel free to use it.
