I will design 3d models for 3d printing with test fit validation


About this gig
Are you tired of receiving unprintable 3D CAD files with incorrect tolerances? Many designers create models that look great on screen but fail to assemble in real life, costing you time and money.
As a professional mechanical design engineer with a fully operational home FDM printing lab, this service guarantees physical printability. I don't just design; I physically test-print critical joints, screw threads, and snap-fits on my calibrated hardware to verify dimensions BEFORE delivery.
What you will receive:
- Fully-constrained 3D CAD modeling (SolidWorks / Fusion 360)
- DfAM (Design for Additive Manufacturing) optimization for supportless printing
- Physical test fitment validation of functional joints
- Professional caliper measurements and photo/video proof
- Watertight STL, STEP, and fully editable native source files
Perfect for enclosures, mechanical links, brackets, and functional prototypes.
Please message me with your drafts or sketches before placing an order!

FAQ
What is DfAM and why does it matter?
Design for Additive Manufacturing ensures the model is engineered specifically for 3D printing, minimizing supports, printing time, and material consumption.
Do you ship the physical printed samples?
Standard packages include high-definition photo/video validation with digital caliper measurements. If you require physical shipping of the prototypes, I can provide a custom shipping offer.
What printers do you use for test-fitting?
I use a calibrated high-precision desktop FDM printer, allowing me to check tolerances down to 0.1 mm.
