Thank you for this fantastic design (Jingle bell musicbox animated christmas tree - Third release).
Unless I am mistaken, one part is missing: the musical mechanism support, under the "PiedCadeauxSapin" part.
Could you add it, please?
Thank you :)

On which design are you asking that Rad0 ?

Hello ALAN, indeed a stl file was missing in my last updated zip file. I have just updated the ZIP file adding the missing UOT+1_V99 stl file, you should be able to download again the zip file to get the missing part.

Thank you for your message and my apologies for this oversight.

good morning, I bought the mechanical calendar, but I see that a piece is missing in the STL files (number 10 of the manual) could you send it to me?
thanks :)
