# Boston Celtics Necklace 3D Print — Index Entry

## Summary

Boston Celtics medallion for Jarod (Donlin medallion series · 2 of 4). Manual-multicolor terraced-tier method on Bambu A1 (no AMS), darker-on-top order: grass green base → white middle → black top. Two manual M600 swaps at L24 (Z 4.6 mm) and L28 (Z 5.4 mm), 0.2 mm layer height.

Unlike Blue Jays, this print did **not** need planning-chat mesh editing. Sam selected a source design that's already mostly-nested (clover + wordmark) and did his own slicer-level pause edits. Worked example of the v1.2 guide §13 F lower-friction mode of the 3-way collaboration.

## Key facts

- 3 colors: Sunlu PLA+ grass green + white + black
- 2 manual M600 swaps (L24 / L28)
- Order: darker-on-top per v1.2 §13 C tier-order tradeoff (vivid green recessed, black surface caps; clean side-walls)
- Hardware: Bambu A1, no AMS
- Recipient: Jarod (Denise Donlin's son) · Deadline: 2026-06-07

## Next steps

1. Print completes — copy source `.3mf` from Sam's Downloads into workdir
2. Sam drops slicer-reported filament weights (refine inventory estimates)
3. Sam drops post-print photo (optional, for the worked-example record)
4. Update v1.2 guide §13 F Celtics row from "validation pending" → "validated 2026-05-29"
5. Move project status → complete

## Status updates

- 2026-05-29: project scaffolded as IN-PROGRESS at start of print. Sam-found source design (no AMS mesh-editing pipeline). 3-color darker-on-top terraced-tier method. Validates v1.2 procedure on a non-interlocking design — second worked example after Blue Jays.
