3D-Printable Marine Bollard with a Modular, Two‑Part Design

A functional bollard featuring a flat, contoured shaft, specifically engineered for 3D printing in two separate components—ensuring effortless printing without the need for complex support structures.

Key Features

• Modular, two‑part design for optimized printability

• Flat, contoured shaft to minimize print time while enhancing structural integrity

• Fastening system with two M5 through‑bolts for secure, reliable assembly

• Standard size of 100 mm, easily scalable to meet any application requirement

Design Advantages

The flat shaft profile enables stable printing with excellent bed adhesion, significantly reducing the risk of print failures. The two‑part design also makes it ideal for printing on virtually any 3D printer, including compact desktop models.

Applications

Perfect for recreational boats, inflatable craft, marinas, naval modeling, or nautical-themed decorative projects.

Technical Notes

• Recommended Materials: PETG or ASA for outdoor use; PLA for indoor or decorative applications

• Fastening: Two M5 through‑bolts
