Why Bruk and Baum bottles use joined G-code
Three Cura-generated toolpaths, different print parameters and a manual join: how River keeps bottle prints continuous and cleaner.

A simple polypropylene bottle printed from joined Cura G-code sections. Its folding cap becomes the seal: when the cap bends into position, water stops coming out.

Bruk and Baum are polypropylene bottles printed from joined G-code sections so each zone can use the settings it needs.
Polypropylene is slow and demanding to print, but it can make watertight one-wall parts, living hinges and food-contact objects when the workflow is controlled.

A collapsible polypropylene bottle made with the same joined-G-code approach as Bruk. The cap folds to seal, and the body can fold into itself like an accordion when empty.



A quiet, USB-powered air purifier that just does its job. Cleaner room air from a printed object that actually looks like it belongs on the shelf — no humming appliance, no exposed electronics.

A full-size ice-pack air cooler built from printed parts, a quiet USB fan and a frozen water pack. Freeze the pack overnight, place it inside, and Yuki sends a steady cooler stream across the desk with very low power use.
