3D printing settingsPrinting notes

Designed for SLA/resin printers only.

Orient at a slight angle and add custom supports to capture the ribbed texture and interlocking ends.

Use fine layer height (≤ 0.05 mm) and a “PLA-like” tough resin for best strength and surface detail.

Assembly & Finishing

No additional hardware required; individual barriers can be glued end-to-end with thin CA (super glue) to form a continuous line.

Parts can be primed and painted with acrylic or enamel paints.
