Gardena Micro Drip 90 degree bend

Those 4.6mm pipes are pretty stubborn and laying them in nice bends only works with force and taking great care to avoid kinks - or buying the clunky corner connectors from Gardena, adding two more connections where leaks can form.

This little helper bends the tube in a 90 degree bend and keeps it there. Prints without supports. Use something rigid like PETG.
