Coin Vortex Mason Jar Lid

Attach this to the top of any standard mason jar, and then enjoy sliding multiple coins down the ramp — watching as they accelerate towards the apex of the vortex.

Printing Notes:

This is an easy print that requires no supports. For some extra fun, attach two or three slides and then try starting multiple coins concurrently!

Assembly Notes:

To attach the slide, get the "Slide Mount" part slightly started on the back of the "Slide" piece first, before attaching it to the funnel. It's designed with a small amount of tolerance so it holds tightly (may need a slight tap to get started). After you have it started, place the slide onto the funnel, and push the slide mount the rest of the way to secure it.
