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.

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, bicycle saddle position measuring tools, holders, housings and other practical parts.

Speaker adapter for a 1997 Honda Del Sol

A custom adapter was developed for a 1997 Honda Del Sol to mount a suitable speaker using the vehicle’s existing fixing points. The project was created as a functional replacement part where an off-the-shelf solution did not fit.

The model was adapted to measured dimensions, mounting-hole positions and the limited space behind the interior panel. Fit, tolerances and access to the fasteners were checked before final production.

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.
