PHASED SHOPPING AND QUANTITIES

One list.
No duplicate purchases.

Amazon is preferred. Seeed Studio and Pololu are the two direct-store alternatives for exact parts not verified on Amazon. Order only after inventory and the relevant design review; a stock listing does not release a build.

$233.56Known fixed-quantity item subset only
$13.22Optional first test spool, if needed
IncompleteMissing quantities, prices and delivered costs remain

How the quantities work

Count physical units

Two motors need two single-motor purchases. Two hubs need one two-hub pack. Two wheels need one pair.

Reuse tools

A caliper or hex tool shown in several steps is the same tool. Check what is owned or included before buying another.

Keep unknowns visible

Fastener lengths, harness contacts and full filament demand depend on measurements. TBD is not zero and not a guessed allowance.

Packs to buy = round up [(required units − confirmed usable owned units) ÷ units per pack], never below zero

Unknown stock receives no deduction in the displayed upper-bound counts. Do not sum step-use quantities. Alternative audio paths and deferred expansion are excluded from the baseline.

STAGE 0

Inventory and shared tools

Reuse suitable owned items; exact tool purchases still need inventory.
