STL Split Into Six Parts

I have a single, over-sized architectural STL that needs to be broken down into six printable sections without losing its original proportions. Please take the file, divide it cleanly into Part 1 through Part 6, and add simple alignment pins and matching holes so the pieces register perfectly once printed.

The model only carries basic surface detail, so there is no need to chase micro-features—accuracy at the join lines and overall dimensional fidelity are the priorities.

Deliverables
• Six individual STL files, clearly named Part 1 – Part 6
• All mating faces prepared with alignment pins/holes that print reliably on consumer-grade FDM or resin machines
• Final parts that assemble flush, recreating the original architectural form without visible gaps or scaling issues

I will test-fit the exported sections in my slicer to confirm build-volume compatibility, then print a quick draft. If everything slots together as intended, we are done; otherwise, I’ll send precise feedback for one revision round.

Looking forward to collaborating with someone experienced in Meshmixer, Blender, Netfabb, or any comparable tool you prefer.
