3D CAD Model of Plastic Accessory

Reverse Engineering + STL/STEP Model of Plastic Clip/Cover from Photos

Project Description

I need an accurate 3D CAD model of a plastic part based on the attached reference photos and approximate dimensions shown with rulers.

The part appears to be a:

plastic clip / holder / cover
possibly related to rifle scope optics or cylindrical equipment

The final model will be used for:

3D printing
prototyping
replacement part production

The part has:

flexible open circular shape
asymmetrical profile
top eyelet / slot opening
smooth internal radii
snap-fit style geometry

Approximate dimensions:

width: ~45–50 mm
height: ~45–50 mm
inner diameter: ~35–40 mm
wall thickness: ~2–3 mm

Multiple photos from different angles are attached, including ruler references.

Deliverables Required
STEP / STP file
STL file
preferably Fusion360 or SolidWorks source file
watertight printable geometry
dimensions matching reference photos as closely as possible
Important

I do NOT want a rough approximation.

I need proper reverse engineering from photos and dimensions.

Experience with:

reverse engineering
technical CAD modeling
injection molded parts
functional plastic components
3D printing

is highly preferred.

Bonus Skills

Extra advantage if you have experience with:

optics accessories
hunting scope components
automotive clips
snap-fit plastic parts
