01.
Mechanical design and engineering
Complete design of mechanical assemblies, mechanisms and special-purpose equipment, with a focus on functionality and manufacturability.
CAD data ready for manufacturing.
From the initial design to production data. I prepare 3D models, technical drawings and files for CNC machining, 3D printing, laser cutting, waterjet cutting and wire EDM.

02 / About me
Šimon Papšo
Mechanical Designer · CAD Engineer
I have worked professionally in mechanical design and computer-aided engineering for more than 10 years. I studied computer-aided CAD/CAM systems at the Slovak University of Technology, giving me a solid technical foundation for designing parts, assemblies and complete production systems.
I work with companies, manufacturers, workshops and individuals in Slovakia and the Czech Republic — from simple part modifications and redrawing older documentation to complex mechanical design projects. I work precisely, with a focus on manufacturability, accuracy and agreed deadlines.
