Chemistry Ring stand adapter

thingiverse

We're setting up marble runs and swapping out books and rulers for adapters made to fit foam pipe insulation onto copper pipes on chemistry stands. The setup looks great and works smoothly. The 102% fitting gives a perfect fit that's easy to move around, while the 100% fitting is a bit too tight. It might not be super practical since masking tape or zip ties could accomplish the same thing, but it was still a hit with the students.
