Hi there !
For fun I made this little puzzle Christmas tree, I want to share it with you.
The model can be printed as a card, or the parts can be printed separately.
Depending on your machine settings, it may be necessary to very slightly increase the scale along the X and Y axis to facilitate assembly.
The model in the form of a card has a dimension of approximately :
X = 250mm
Y = 274mm
Z = 2mm
Have fun !
I wish you a Merry Christmas !
