Replacement toggle switch cap for older (1970s?) Technics hifi receivers. The service manual that I have lists it as part number SBD7.

Created to fit an SA-400 receiver, but it appears to be common to other contemporary models - looking at photos, the SA-500, 600, 800 and 1000 all appear to use the same part.

The cap is a friction fit onto the switch stem, and depending on your printer and filament, you may need to adjust the dimensions of the slot to suit. The included FreeCAD document has all the dimensions brought out into a spreadsheet, for easy editing.

For best results, print upright, with the slot at the bottom. May need a brim due to its small footprint. 100% infill is recommended.

Took about 20 minutes to print at 0.12mm resolution.
