This music box holder is exclusively designed for the Kikkerland brand (Make Your Own Music Box Kit). The threaded holes are carefully calibrated so that the base could fit the inner part's bolts. Please don't adjust the general size during settings. Hope you could have a good experience.
If you have any trouble while assembling the music box, please feel free to make comments.

Printing:

Ring - Infil to add weight, supports needed for spade inset. Letter embossing doesn't need it.
Spade - Infil to add weight, no supports
Letters - Print flat, already scaled to fit nicely in the embossing
Star - Infil to add weight.

Full print with 4x4x4 walls/top/bottom and 38% infil came to about 48g in weight.

Glue in lettering and spade. Star may need minor sanding but should push fit into the space tightly and not need anything else to secure it.
