Build support

TPU/PTFE completion kit

ConceptP1 - High - Urgency 4/5Build-completion support item

Roadmap item, not a released accessory yet. Files, pricing, checkout links, and compatibility claims wait until the validation gate passes.

Requirement

Problem: Some buyers cannot print TPU parts or do not know which PTFE/couplers are needed.
Why now: This is close to a paid-user blocker because users can print rigid parts and still be unable to finish a working system.
Exact requirement: Package or document the exact TPU parts, PTFE tube spec, couplers, and routing hardware needed after printing the rigid files.
Compatibility: A1 and A1 Mini release; final Mini tube lengths should follow the Mini routing notes.

Release Gate

BOM, supplier links, and 8-slot routing diagram are stable.

Acceptance criteria

Lists exact TPU parts, PTFE spec, couplers, and quantities for 4-slot and expanded builds.
Explains what a buyer can do if they cannot print TPU 95A.
Separates required completion parts from optional upgrades.

Launch assets

BOM table with supplier-neutral specs.
One routing photo or diagram reviewed against the mechanism reference.
Clear wording for buyers who cannot print TPU 95A.

Prototype Plan

Turn the BOM and buyer routing checklist into a kit-ready list, then decide whether this ships as a docs-only guide, affiliate list, or physical pack.

Next build steps

Build a supplier-neutral kit checklist from the current download manifest and manual.
Verify quantities against a full 4-slot and expanded 8-slot build.
Decide whether the first release is a docs-only checklist, affiliate list, or physical pack.

Measurements needed

PTFE tube length range for 4-slot and expanded 8-slot A1 builds.
Exact coupler/Y-splitter count for current release packaging.
TPU printed-part list, mass, and preferred durometer.

Safety Boundaries

Must not imply rigid parts are optional if TPU 95A parts are required for reliable drive contact.
Must not sell or recommend unverified PTFE routing for A1 Mini before measurements exist.
Must keep supplier references separate from any required safety or warranty disclaimer.

Evidence source

Buyer comments ask what extra materials are needed and how to finish the 8-tube routing.

Validation Tests

Quantity reconciliation

Cross-check the kit list against one full A1 build and the buyer download manifest.

Pass: No required non-printed part is missing and optional parts are clearly separated.

Routing completeness check

Route every listed PTFE path on a real A1 build using only the kit checklist.

Pass: All configured slots can load and unload without extra unlisted fittings.
