You want your 3D printer to stop leaking plastic between moves. This test piece shows you exactly how much ooze your printer makes, so you can fix it.

The Ooze Test Piece is small and quick to print. It works for any extrusion system, especially Bowden setups that tend to leak. Print it, watch where the plastic drips, then adjust your retraction settings and try again. Each test takes just minutes, not hours.

This design comes from Erik's work on reducing ooze in RepRap printers. It pairs well with software that pulls back plastic between moves. The piece needs no support, which keeps your test cheap and fast.
