About this gig
Turn your idea into a physical product without taking risks on expensive tooling. I don't just "draw in 3D" I develop robust, scalable mechanical solutions.
I'm Anton, a German R&D engineer specializing in product development & Design for Manufacturing (DFM) for startups and enterprises.
My Core Expertise:
- Mass Production DFM: Injection Molding, CNC & Sheet Metal (draft angles, wall thickness, undercuts).
- Complex Enclosures: Housings for PCBs & IoT devices with precise tolerance chains.
- Rapid Prototyping: Smart design for FDM/SLA/SLS to test your MVP fast.
Why work with me?
- German Engineering: Precision, reliability & clear communication.
- Agile Iterations: Transparent milestone-based workflow.
- IP Protection: I will happily sign an NDA before we start.
Important: Hardware development is highly individual. Please contact me before ordering to discuss your custom milestone plan!
(Note: I optimize to industry DFM standards. Final manufacturing liability and tool-specific material adjustments remain the responsibility of the client and their chosen manufacturer.)

Hey there! I am Anton, a German engineer coming from the fields of production technology engineering and product development. I have worked for big industrial companies and innovative startups, got a degree as an electronics technician and earned a lot of experience working for multiple customers and on many big projects. Furthermore, I cofounded a company which specialized in hardware development and production. I do a lot of engineering daily to help companies launch and make their vision into a real product. So just tell me what you want to get to build, and I will make it possible.
FAQ
Will you sign an NDA?
Absolutely. Your intellectual property is your most valuable asset. Send me your standard NDA, or I can provide one, and we will sign it before you share any sensitive technical details.
Do you also handle the physical manufacturing?
I provide professional, manufacturing-optimized CAD files (STEP, 2D drawings). I prepare technical docs to ensure a smooth sourcing process and minimize feedback loops with your supplier. Final liability remains with the client.
Is my 3D-printed model ready for injection molding?
Usually not. 3D printing is forgiving. Molds require specific draft angles, wall thicknesses, and undercut resolutions. I re-engineer designs to significantly reduce the risk of expensive tooling mistakes.
How do you handle revisions?
For larger projects, we use milestone approvals. We review the CAD at specific stages. You provide feedback and approve before we move to complex DFM details. This minimizes major late-stage changes.
What source files will I receive?
Native CAD (Inventor/Fusion 360), neutral 3D files (STEP, STL), and technical 2D drawings (PDF) with required manufacturing tolerances.
