I will design 3d cad models from 2d drawings into stl, 3mf or step for 3d printing


About this gig
Every 3D project is unique. For complex mechanical assemblies, custom product series, or full product development, please message me before placing an order so I can provide a tailored custom offer!
Hi there! If you have an idea you want to see printed, Im here to help you out.
In my day job, I work as a Mechanical Design Engineer and I'm a 3D printing enthusiast, spending a lot of my free time tinkering with my Bambu Lab A1. This mix of professional engineering theory and hands-on home printing helps me create models that actually work in the real world, not just "look good" on a screen.
How I can help you:
- Turn your sketch into reality: Send me a hand drawing or a photo, and I'll build a print-ready 3D model. (I don't do character Sculpture modeling)
- Optimize 3D for print: I'll optimize your 3D to be optimal for printing.
- Fix or modify STL files: If you have a file with mesh errors or need to change a hole or a dimension, I can solve it quickly.
- Optimize for success: I'll adjust tolerances and wall thicknesses specifically for your printing process so you don't waste filament on failed prints.
- Functional parts: I design enclosures, mechanical joints, or replacement parts that

FAQ
What files do I need to provide to start?
You can provide hand-drawn sketches with dimensions, photos of an existing object, or a 2D technical drawing. If you have an existing 3D file like an STL that needs modifications, please send that as well.
Can you modify or "fix" my STL file?
Since I work with professional engineering software (CATIA V5/SolidWorks), I don't "sculpt" meshes. Instead, I use your STL as a reference to re-create a clean, solid CAD model (STEP/Part file, depending of the complexity). This ensures the part is geometrically perfect and easy to manufacture.
Will the design be ready for 3D printing?
Yes. As an active practitioner of 3D printing with a Bambu Lab A1, I design with FDM/SLA constraints in mind. I optimize wall thicknesses, tolerances for moving parts, and orientations to minimize supports and ensure a successful print.
What file formats will I receive?
For the 3D printing part, you will receive a high-quality STL or 3MF file. Additionally, I provide a STEP file for future engineering needs.
Can you design complex mechanical assemblies?
Absolutely. With 9 years of experience in mechanical design and a Master’s degree in Road Vehicle Engineering, I specialize in functional mechanisms, enclosures, and parts that need to fit together perfectly.
Do you offer 3D printing services and shipping?
Currently, I provide the digital 3D models and engineering consulting. However, because I use the same hardware as many professional makers (Bambu Lab), I can provide you with the exact print settings or 3MF project files to ensure you get the same result I would.
