Singing Belle (Bell)

Yet another singing prop for 12mm RGB pixels. This time a bell. It is built such that there is a 2mm wide border
along the edges of the pieces to a hight of 10mm and the thickness of each piece 6mm. The pieces are quite strong at 6mm.
Each part is labeled with an identifier on the front face that is recessed 2mm into the part.

This zip file contains the STL to make the bell shown in the Assembly picture.
The bell is about 1155mm tall and 1003mm wide (46" tall and 40" wide).
All the parts will fit on an Ender 5 pro bed.
The bell holds 206 pixels.
There are a total of 33 pieces. There are two test pieces included to set up your printer and don't attach to the prop.

Printer:
I have been printing in PLA+. I'll have to see if it holds up outdoors!
I use CURA (v4.80) as my slicer. I set the "Horizontal Expansion" setting to -0.21mm. This allows for a snug fit for the joints on my current printer setup.
I recommend printing the test pieces to see what your setting mi
