urn your 3D printer into a mechanical powerhouse! 🛠️

This is not just a display model—this is a fully functional, screw-driven bottle jack designed to demonstrate the power of 3D printed threads and mechanical engineering. Whether you want to learn about mechanics or just show off what your printer can do, this model is a must-have for every maker.

Key Features:

• 100% 3D Printed: No external hardware, bolts, or bearings required.
• Fully Functional: The screw mechanism is optimized for smooth movement and lifting.
• High Strength Design: Engineered with reinforced walls and optimized thread profiles to handle actual weight (test it at your own risk!).
• Print-in-Place Ready: Designed for easy assembly and minimal post-processing.

Recommended Print Settings:

To ensure the strength and functionality of the jack, I recommend the following:

• Material: PLA+ or PETG (for better durability).
• Infill: At least 40-50% (Gyroid or Cubic recommended for structural strength).
• Wall Loops: 4 or more to ensure the threads don't shear under pressure.
• Layer Height: 0.16mm or 0.20mm for smooth thread operation.
• Supports: Not required (designed with 3D printing tolerances in mind).

Assembly Instructions:

1. Clean the threads from any stray plastic or blobs.
2. Apply a small amount of lubricant (silicone grease or even a bit of oil) to the screw for maximum smoothness.
3. Screw the top piston into the base.
4. Test it out! Start with light objects and see how much your print can lift.
