Print and test-fit first PETG frame on a nursery sapling

[Commons-Lab-1]

Goal

Print all frame components in PETG and verify fit around a real sapling.

Steps

1. Export all STLs from mechanical/frame-3dprint/treeguard-frame.scad
2. Print: 3 spines, 9 ring segments, 1 enclosure, 3 stakes, 1 solar mount
3. Assemble with M3 brass inserts + security Torx
4. Test-fit around a nursery-bought sapling (150-200mm trunk clearance)
5. Check: trunk clearance, stake stability, enclosure clip, ring alignment

Acceptance

• Frame stands free without trunk contact
• Ground stakes hold in real soil
• Electronics enclosure clips/unclips cleanly
• Ring segments swap independently
• Photos taken from front, side, top angles
