Before automated conveyor belts, manual mechanisms like this one transformed raw material into processed form through continuous rotation — a true conveyor of the past. 

A fully functional 3D printed mini meat grinder model with rotating handle and screw mechanism.

Perfect as an educational demonstration of how a meat grinder works — or as a fun decorative model for your kitchen or workshop.

The screw and handle rotate smoothly inside the body.

Includes:

• Body
• Screw (auger)
• Handle
• Front cap with locking thread
• Inner star and disc plates

Recommended settings:

• Material: PLA+ / PETG
• Layer height: 0.2 mm
• No supports needed
• Print all parts at 100% scale for correct fit

⚙️ Designed as a demonstration model — light rotation works perfectly, but real food processing is not recommended unless reinforced and glued.

Personal use only.
