Four identical parts go together to make a symmetric sliding mechanism. It is a difficult puzzle to put them together, and even more difficult to have them slide together so that they all have the same offset relative to each other.

This worked well printed vertically with no support.

This is joint work with Saul Schleimer.

Very nice. Any chance of making caps for the free ends?

These are solid, for better fdm printing. So there are no holes to plug a cap into. I guess one could print a solid cap, and drill holes into the cap and the rods, and glue with a pin?

Makes sense. Very nice piece of work. Your stuff is amazing.

Glad you like it!
