Merten Designs

Functional parts, rapid prototypes, and design support for inventors, builders, and small teams that need capable engineering help without big-company friction.

Small business attention. Technical execution.

From a rough idea to a tested physical part.

Merten Designs LLC supports decorative and functional 3D printed parts, with a strong focus on practical components, fixtures, prototypes, reverse-engineered replacements, and engineering-grade material choices.

Bring an existing file, a napkin sketch, a broken part, or a product idea. The goal is to help you move from uncertainty to something you can hold, test, revise, and manufacture.

Capabilities

Design and manufacturing support built around real parts.

01

Functional 3D Printing

Prototypes, brackets, housings, jigs, fixtures, replacement parts, and end-use components using material choices matched to the job.

02

CAD Design

Concept modeling, fit checks, design-for-print improvements, drawing cleanup, and iteration from rough concept to usable geometry.

03

3D Scanning

Capture physical shapes for reference, inspection, reverse engineering, restoration, and parts that need to match existing real-world surfaces.

04

Product Development

Early prototypes, test articles, design revisions, small-batch manufacturing planning, and hands-on support for inventors.

Materials & applications

Practical material guidance for practical use cases.

Engineering-grade options PETG, ABS, ASA, TPU, Nylon/PA, Polycarbonate/PC, carbon-fiber or glass-fiber reinforced composites and other application-driven choices.
Design intent Strength, temperature exposure, fasteners, tolerances, surface finish, and service environment.
Project types Functional prototypes, production aids, fitment checks and custom components.

Portfolio

Project examples are being prepared.

A public portfolio will be added as project photos, summaries, and NDA-safe examples are consolidated.

Functional Prototypes

Proof-of-concept parts, test revisions, and design validation builds.

Scan-to-CAD Work

Measured references, reverse engineering, fitment, and restoration support.

Manufacturing Aids

Jigs, fixtures, templates, workholding, and small production tools.

Products

Functional product lines are in development.

Merten Designs is exploring practical, small-batch products built around useful printed parts, custom-fit designs, shop aids, and durable everyday problem solving.

Automotive

Custom-fit, non-critical accessories and functional printed components.

Custom Tools & Jigs

Fixtures, templates, organizers, workholding aids, and task-specific shop tools.

Custom Product Designs

Original parts and product concepts designed for fit, function, testing, and iteration.
