Prusa Commercial BTS: Adapter Collar

This collar adapter was originally designed and printed for use in the official Prusa Core One commercial, where stable counterbalancing was critical for controlled camera movement.

The adapter allows standard gym weight plates to be securely mounted as counterweights in filming rigs. During production, it was used to fine-tune balance on motion setups, helping achieve smooth, repeatable camera moves without the need for dedicated film counterweights.

Why Use Weight Plates?

Gym plates are:

• Affordable and widely available

• Modular and easy to stack

• Dense and compact

• Ideal for precise counterbalancing

Instead of investing in specialty counterweights, this adapter lets you use readily available equipment in a professional production environment.

Use Cases

• Balancing camera cranes

• Stabilizing sliders

• Counterweighting vertical rigs

• Custom DIY studio builds
