Design Concept: The Paw-Track Interactive Engine
The Paw-Track is a high-performance, motorized string-play system designed to automate feline enrichment. Unlike generic toys, this system features a 3D-printed paw-shaped chassis that houses a high-torque DC motor and a custom tangle-free spool. It utilizes a closed-loop string mechanism to simulate the erratic, high-speed movement of prey, triggering a cat's natural hunting instincts.

Key Engineering Features

Granular Speed Control: Equipped with a precision manual potentiometer (knob), allowing owners to fine-tune the chase speed from a slow crawl to high-velocity "sprint" modes.
Industrial Power Core: Powered by a rechargeable 12.6V 3S battery configuration with an integrated BMS for long-lasting play sessions and safety.
Modular Anchoring: Features secondary paw-shaped passive guides that allow the user to create custom geometric "chase zones" on any floor surface.

Printing & Material Specifications

Use the 3mf file for easy print a made all the settings that you will need for each part
Materials: Recommended PLA+ or PETG for high impact resistance.
support are required only for the Handels else the model is support free
for the secondary paw you will need to make a pause before the lid get closed so you can fill the infill with sand or cat litter sand
check for the motor size because it came with defiance sizes like mine came small so i had to scrow it to the lid and make it haver
use M3 Screw for everything
