Replacement part for watch winder (updated)

Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:3385971.

The keepers on the watch adapters from my watch winder broke all after some months of use. Glueing them back into place only worked for a very short time. So I tinkered the part together in FreeCAD, the adapters now work perfectly again :) update new version uploaded :)
