Field notes

The interface lays out a sequence from model upload and printer selection through settings, slicing, estimates, and G-code download. Its visible controls cover model orientation and scale as well as print parameters such as wall count, supports, temperatures, and adhesion. The site says the model stays in the browser, while the slicer engine and printer profiles are fetched from its server.
