A resin store that starts with the printer

Poligon SLA sells photopolymer resin for 3D printers. Labs and studios come back every few weeks, and they come back for the same bottle.

1. Printer first. A buyer knows the model on their bench and does not know the resin family it belongs to. Printer, then the compatible list: the shortest way to the right bottle.
2. Type as the second door. Tough, castable, washable stays a filter, because the machine already narrowed the field.
3. One spec card shape. Every bottle shows the same rows in the same order, so a lab compares two resins without holding two tabs open.
4. Checkout for the repeat order. Whoever reorders the same bottle goes straight to it: the store keeps that last choice in reach.

Consumable sellers win on the second order. Build the shop so that order takes the least time.
