Service routing — decision tree

1. User reports issue via app / phone / email

Triage by WanderTherm Support (Ambassador-staffed):

CR2477 cell low → direct to WanderStore $7 / 2-pack OR any local store CR2477
Cosmetic face-plate (scratch, fade) → direct to WanderStore $19 face-panel swap
Firmware / software issue → remote diagnostic + reset + OTA update
Hardware fault < 30 days (DOA / early failure) → ship-to-warranty send-back, no charge
Hardware fault 30 days - 1 year (in warranty) → Ambassador send-back, no charge
Hardware fault in extended warranty period (3yr / 7yr opt) → Ambassador send-back, small admin fee only ($25)
Hardware fault > 7 years → user pays parts + $25 service fee; or DIY with STL + schematic + Community repair

2. User can DIY

wanderverse.com/repair has:
Full schematics (PDF + KiCad source + Gerber)
Open STL files (CC-BY-SA) for face plates + bracket
Video guides per repair task
Fasteners + bit list
Parts availability map
Local repair tech finder (trained on WanderTherm)
Spare-parts store direct from WanderStore

3. Ambassador send-back (5-day turnaround)

User submits ticket
Ambassador ships prepaid label
Unit arrives at Ambassador depot
Ambassador diagnoses + repairs + QA + hipot retest + Matter cert verify
Ships back within 5 business days
Cost: $25 service fee + parts + shipping (waived in-warranty)

4. Factory repair (if Ambassador can't fix)

CR2477 coin cell replacement — user procedure

Per GUIDE.md: 1. App alerts "Replace backup cell when convenient — no urgent action required" 2. User opens magnetic face panel (4× T5 Torx loosen) 3. Slides old cell out; inserts new (positive-side up, silkscreened) 4. Closes face panel; T5 tighten 5. App confirms voltage + updates next-replace estimate

Cell sourcing:

WanderStore: $7 / 2-pack (Community Pool feed)
Any local store: CR2477 is a commodity; ~$3-5 per cell
WanderVerse Founding Members get free 2-pack at year 6 (proactive ship)

---

Face-panel color refresh

Per GUIDE.md:

Cream (default) → Slate ($19) — swap in 60 sec
Cream (default) → Custom Ambassador-finished ($75) — order custom face panel
Custom engraving on existing face panel → send-back service ($25 + $39 engraving)

What's in this folder (planned — final files ship with industrial-design team after 2027-Q1)

WanderTherm chassis-adjacent STLs

Note on chassis itself: the cream-anodized aluminum chassis is NOT 3D-printable as a structural replacement (aluminum CNC + Type II anodize is the only way to get the saffron-pinstripe permanent integration + the EM/thermal/durability properties). Users requesting chassis replacement must order from WanderStore or Ambassador depot. STL files cover face plates + brackets + accessories.

Face panels (CC-BY-SA — print your own)

face_panel_cream.stl — main cream face panel (88mm round, 2mm thick) — print in cream PETG or paint after print
face_panel_slate.stl — slate variant (same geometry, color-tinted print)
face_panel_blank.stl — no engraving / no signature — for users who want to engrave their own
face_panel_pediatric_lockout.stl — face panel with central button removed (prevents kid-toggle of mode)
face_panel_haven_admin.stl — face panel with admin-mode-indicator marking
face_panel_braille_setpoint.stl — face panel with raised Braille indicating current setpoint range — accessibility
face_panel_community_artdeco.stl — Ambassador-designed Art Deco variant (community contribution)
face_panel_community_minimalist.stl — Ambassador-designed minimalist variant
face_panel_community_pride_pattern.stl — pride-flag-themed variant (community contribution)

Note on face panels + magnets: STL files are the cosmetic shell only. Users print the shell, then transfer the 4× N42 magnets + T5 Torx insert nuts from their existing face panel (60-second swap). Replacement magnet + insert kit available from WanderStore for $4.

Wall-mount bracket STLs

wall_bracket_universal.stl — universal bracket (4×4 single-gang, 2×4 round, EU 60mm)
wall_bracket_eu_pattress.stl — EU recessed pattress box variant
wall_bracket_surface_mount.stl — surface-mount with cable cover (for installs without recessed box)
wall_bracket_extender_15mm.stl — adds 15mm depth for old-build deep wallboxes
wall_bracket_extender_25mm.stl — adds 25mm depth

Drilling templates (printable cardboard alternatives)

drill_template_4x4_singlegang.stl — flat printable drill guide
drill_template_2x4_round.stl — flat printable drill guide
drill_template_eu_60mm.stl — flat printable drill guide

Coin cell access tool

t5_torx_handle.stl — printable handle for T5 Torx bit (in case user lost the included one)

Tool holders + organizers

repair_kit_caddy.stl — printable caddy holding T5 + T10 bits + spare CR2477 + spare magnets
wall_mount_dock_for_repair_kit.stl — under-cabinet wall mount for the caddy

EU OpenTherm install accessories

boiler_termination_clip.stl — strain-relief clip for OpenTherm bus cables at boiler end
cable_management_strain_relief.stl — generic cable strain-relief

HAVEN deployment accessories

lock_cover_plate.stl — covers face-panel screw access for resident-tamper-resistant install (admin uses different bit pattern)
multi_unit_alignment_jig.stl — for HAVEN bulk install where 5+ thermostats need consistent alignment

Print recommendations

Print settings

Layer height: 0.15-0.2 mm (face panels need finer for tactile feel; brackets are 0.2mm fine)
Material:
Face panels: PETG (preferred) or PLA — cosmetic only; no fire-safety requirement (interior, not in airflow)
Wall bracket: PETG or ABS — structural; PETG fine for residential
Drilling templates: PLA fine; printed for one-time use
Tool holders: PLA fine
Coin cell access tool: PLA fine
Infill:
Face panels: 30-40%
Wall brackets: 60-80% (structural — must hold thermostat against wall)
Tool holders / drilling templates: 15-20%
Supports: tree supports for face-panel magnet pockets; standard supports for bracket undercuts
Color recommendations:
Face panels: cream (default — Pantone Warm Gray 1C compatible) or slate (Pantone Cool Gray 11C)
Wall brackets: standard black or color-match to chassis
Tool holders: any

Printer requirements

Build volume: 110 × 110 × 50 mm minimum for face panel; 120 × 120 × 50 mm for wall bracket
Direct-drive extruder recommended for PETG
Heated bed for ABS

Annealing (optional for improved strength)

ABS face panels benefit from mild annealing (90 °C for 2 hr) for dimensional stability if used for wall bracket

---

Fit + tolerance

All STLs designed for ±0.1 mm fit tolerance
Face panel magnet pockets: 6 mm × 2 mm × 2 mm depth (for D33 N42 6mm × 2mm magnets)
T5 Torx insert pockets on face panel: 4 mm × 8 mm depth (for M2 × 8 brass thread inserts; ~$0.10 each)
Bracket screw holes: M3 clearance (3.2 mm diameter)
Threads: not modeled — users tap or use brass inserts

---

Compliance + safety

No fire-safety requirements for face panels (cosmetic only; not in HVAC airflow path; cannot be ignited by normal use)
Wall bracket should use PETG or ABS (structural; not PLA which can fail at 60°C if installed near a heat source)
Coin cell access tool can be any material — temporary use
No food-contact, no UV outdoor use (all parts indoor)

---

Version history

Version	Date	Notes
v0 (scaffold)	2026-04-24	Scaffold + placeholder STL list — actual STL files generated at 2027-Q1 after industrial design team hire
v1.0 (post-EVT)	2027-Q1 target	First complete STL release — all face panels + wall brackets + tools
v1.1	2028-Q1 target	Community contributions merged + EU pattress depth variants

---

How to use

1. Find the part you need — search this README by tier + part name 2. Download the STL (once v1.0 ships) 3. Print per recommendations (material, layer height, infill) 4. Transfer hardware (magnets + T5 Torx inserts from existing face panel; or buy replacement kit) 5. Assemble — magnetic snap-fit + T5 Torx capture 6. If a part doesn't fit: file an issue on GitHub — we'll investigate the fit or tolerance issue

---

Image-alignment requirement

Per the canonical hero render (wandertherm-hero-2026-04-24.png):

Face panel printed STLs are cosmetic; they do NOT replicate the saffron pinstripe (which is anodized into the aluminum chassis bezel — a permanent finish, not a printable feature)
The "subtle saffron arc" indicating heating mode is driven by Cree saffron LEDs behind the bezel — not visible on face-panel STLs (face panel is the front 88mm disc; bezel is the outer 100mm ring of the aluminum chassis)
STL face panels sit inside the bezel ring; they are inherently centered + circular
Color match: community face-panel prints in PETG/PLA approximate but cannot exactly match the cream-anodized aluminum finish — that's by design (DIY = adjacent, not identical)
