Bang & Olufsen blue-case test gear rubber feet replacement

During the 1970-1980's, Bang & Olufsen produced a number of electronic test instruments, best ones with the blue casework. Perhaps the best known are SN series of bench power supplies, RV series of bench multimeters and RT variacs.

While restoring my TG7 oscillator, I needed a new rubber feet as one was missing (and the rest were badly deteriorated) so I modeled this after the original part. Should be close enough and works with the original screws.

Printed in flexible TPU it has somewhat rubber-like appearance but plain old PLA works as well (in that case you might want to add felt pads to prevent scratching the surface the feet rest on).
