3D-printable replacement/augmented feet for the Rigol DS1000Z series oscilloscopes. At least on my scope, the feet were very stiff to deploy, and both have now broken, one completely off. These feet firmly clip into place over the folded original feet (whether broken or not). With rubber pads on them, they're even a bit more sturdy than the original. Won't easily come off unless you're trying.
Best printed upside-down either using regular old bridging, or with support for a cleaner inside finish (not required).
