Amp push-button for NAD/Proton

Just a little replacement part for my amp, a vintage Proton 520. There are a lot of parts in common with the amplifiers sold in the same years by NAD, as they where assembled in the same factory.
For a good look i suggest using a 0.25 mm nozzle.
After print finish: a little water-sanding, using 400 or finer grit sandpaper.
Final polishing of the exposed faces can be improved or using car polish or by heating (re-fusing the PLA)
