The original stand of the Moog Claravox has 3 wooden legs that fit in sockets of a metal base, with the help of plastic plates. The legs sometimes sit very loosely in their sockets. Only the weight of the Claravox and the stand itself keeps them in place. Moving the Claravox theremin may, in extreme cases, cause the legs to fall out of the metal base.
Moog Music already glued a plastic H-shaped layer between the two plastic plates bits that are screwed on the wooden legs. As this is sometimes not enough, it can be a good idea to add some more material. For this I made an exact copy of Moogs H, and printed them out in elastic TPU on a 3D printer.
As not all gaps are equally wide, the set fillings contains 9 H-shapes in 3 different ticknesses: 0.3 mm, 0.5 mm and 0.7 mm. The fillings can be combined to close larger caps.
When installing the H fillings. take care not to overtighten the screws, as the plastic plates may break.
