Summary

Adapter for a Technics turntable model SL-D2 to allow spring isolator feet to be used as replacement rubber feet. The normal diameter of these feet is about 42mm, while the inside diameter of the hole for attaching the factory feet is about 33mm. This can be securely screwed to the body of the turntable within the inset footprint, and the new replacement foot can be affixed to the bottom of the adapter.

Minimal infill should dampen some vibration. Attach the new feet with pan head #6 3/4” screws or your local equivalent. The factory screws are funky, will not fit these feet, and not worth looking for exact replacements.

Generics isolator feet do not attach, but use rubber pads on either side for slide resistance. These are the ones pictured (affiliate link).

(Previous version of this thing was for the wrong model. This is for the SL-D2 and not the SL-B2)
