This model is based on a digital reconstruction of Michelangelo's Pietà, located in St. Peter's Basilica in the Vatican. The model not a 3D scan of the statue, but a hand-made digital reconstruction using a scan as a base, meaning the model is very high quality with smooth edges.

I have modified the geometry slightly to fix an error in Bambu Studio and exported it in multiple sizes at 0.16mm layer height. There are 3 STL's in the profiles, which are the front of the bust, the back of the bust, and 4 connector pegs. The front of the bust will stand on it's own and balance well without the back of the bust attached, but it may look silly without the back. I have included 1 and 2 plate versions for the small and medium profiles files. This model can be printed without supports and with no surface defects due to overhangs or bridging.

There are 3MF files with plates that have 3 sizes models available:

• Small: 130mm tall (A1 mini compatible)
• Medium: 174mm tall (A1 mini compatible)
• Large: 225mm tall (A1 standard/P1/X1 series only)

Notes

Depending on your filament and calibration, the tolerances for the connector pegs may be too loose or too tight. When inserting the pegs, there should be only a little resistance, with the ability to remove the pegs if needed. If you find that the connector pegs are too big/small, using Bambu Studio/Ocra Slicer to resize in 1% increments. I suggest printing one connector peg first and then checking the sizing before printing all 4, but it's a they're a quick print and don't use much filament. You may need to tap the pegs with a hammer at the very end of insertion to ensure they go all the way in.

I have printed multiple layer height profiles of this model and I found that there is next to no difference in quality once you drop below 0.16mm, so I am keeping 0.16 for quality overhangs and faster prints. Feel free to adjust as you like.

The filament used in the pictures above is Eryone Marble PLA (no affiliate or sponsorship). I think it has a mix of marble and stone with a very matte finish that completely erases layer lines, even at close inspection. I print that filament using the built in Bambu Matte PLA filament profile and it works great and prints at great speeds. The filament is pictured on Amazon as having a plastic spool, but it is actually carboard. You will need a spool adapter to avoid issues in your AMS. I have made on already, linked here.

The provided profiles use grid infill. If you run into issues with the grid infill colliding with the print head, switch to using gyroid infill. I didn't personally have this issue but I know some people run into this problem.
