Electrolux Ergorapido Articulation Retaining Ring

The plastic retaining ring of our ErgoRapido lost its 'claws' over time of heavy use. To fix the otherwise perfectly working vacuum cleaner, I designed a more rigid version of the retaining ring, hopefully others can find it useful also. I printed this in PLA, let's see how it holds up, if it fails, I'll try PETG or Nylon for a new version.
