3D printed hockey puck - only 2 pieces

This indoor hockey puck is designed to be safe for home use while still delivering fast, smooth, and satisfying gameplay.
The puck glides using three steel balls mounted underneath, originally designed around 25 mm balls, but it can also work well with slightly smaller or larger sizes depending on the desired speed and feel. This makes the design flexible and easy to customize.

Its movement system allows the puck to slide smoothly across flat surfaces while reducing friction and minimizing the risk of damaging floors or furniture, making it ideal for indoor environments.

The entire design is made from only 2 printed parts, keeping the assembly simple, lightweight, and reliable. Despite the minimal design, the structure is extremely durable and impact-resistant thanks to the use of PETG filament, which provides excellent toughness, flexibility, and long-term resistance to repeated hits and collisions.

The open outer frame also helps absorb impacts while giving the puck a unique futuristic look. The result is a strong, safe, and highly functional indoor hockey puck that combines speed, durability, and simplicity in a compact design.
