Prototypes & Small Batches

Functional prototypes, custom adapters and small production runs developed from a real problem, an existing part, photographs or measurements.

Zagreb / Veliko Polje

One piece is often enough to start

Not every project needs to begin with mass production. One functional part is often enough to verify dimensions, installation and real-world use before making additional units.

Examples include a speaker adapter for a 1997 Honda Del Sol, a 150 to 100 mm ventilation duct adapter, a bicycle saddle-position measuring tool, mounts, enclosures and other practical parts.

What we make

What is possible

Functional prototypes

Models for checking shape, dimensions, ergonomics or basic function before larger production.

Adapters and replacement parts

Custom parts when a standard solution does not exist or does not fit.

Small batches

Repeatable smaller quantities for companies, clubs, workshops and special projects.

Bearhill Lab

Prototypes & Small Batches

Not every project needs to begin with large production. Often one functional part, adapter, measuring tool or test model is enough to validate an idea and avoid a more expensive mistake.

We work on projects such as speaker adapters, custom electronics and sensor enclosures, measuring tools, holders and other practical parts.

Speaker adapter for a 1997 Honda Del Sol

For this project the client supplied a finished STL for a 1997 Honda Del Sol speaker adapter. Bearhill Lab did not design or redesign the 3D model; our role was the final production of the functional part.

The adapter was produced in a material suited to elevated temperatures and the conditions inside an automotive door. Because the client supplied a usable STL, the work focused on production and selecting a material suitable for the intended environment.

150 to 100 mm ventilation adapter

This transition adapter connects a 150 mm ventilation duct to a 100 mm flexible hose. The transition geometry was designed to remain compact, rigid and straightforward to install.

The prototype verified the real fit on both diameters before any additional units were produced. This approach is useful when standard duct reducers do not fit the available space or connection method.

Custom enclosure for an air quality sensor

This project involved the development of a custom enclosure for an air quality sensor, designed around the actual electronics and the real internal component layout. The enclosure was built around the sensor’s electronics and actual internal component layout.

The enclosure was adapted for USB-C ports, a dedicated LED indicator position, and the required internal arrangement of the components. In addition to the base and lid, a translucent outer cover was also created to give the device a cleaner appearance while protecting the electronics. This type of enclosure work is available for prototypes, sensors and small-batch electronic devices.

FAQ

FAQ

Do I need a finished model?

No. An idea, photo, sketch or description is enough for an initial estimate.

Can I order one piece?

Yes. We make one-off pieces, prototypes and small batches.

How long does it take?

It depends on complexity and quantity. You receive an estimated lead time after we review the inquiry.

Do you ship to the EU?

Yes. We ship across Croatia and the EU.
