I modified the original files to be separate as they should be for easier printing and scaling. Additionally I repaired the damaged parts which would previously be impossible to print.
Printer:
Custom i3
Rafts:
No
Supports:
No
Resolution:
Any
Infill:
10-20
Notes:
Supports only needed for the Back portion of the print. The rest will print without supports or any special settings. Ensure min layer time is high enough since most parts end in a small point. Additionally, both parts of the Pie tend to warp at the far edges. A brim may help, but expect a slight gap when gluing together. Filler can be used to fix this if the model is painted.
Assembley
Assemble all parts using an adhesive. Super glue works well and sets quickly.
