Lithophane Ornament Cap Redesign

The ItsLitho lithophane ornaments have a cap part to attach the ornament to the lights. My friend's ornament broke while trying to attach it, so I redesigned the attachment/cap to be a screw for strength & ease of connection. Works with the same size lights that the original part worked with.

The male side needs to be glued over the stem of the ornament (I used Tacky glue). Prints without supports (flip female cap part upside down) but print with brims for stability. Printed at 0.15mm layer height, but 0.2mm would probably be fine. Screwing & unscrewing the parts may be necessary to smooth the print & make it easier to use.
