Hızlı Açılan Kilit Mekanizması Tolerans Testi Ücretsiz Demo Ücretsiz 3D Modeller

📌 About the Model
This is a free demo module of the unique bayonet locking mechanism from my flagship project — the Fully Articulated Industrial Robotic Arm (100% 3D Printed).

This assembly is engineered based on industrial quick-release systems. It uses a custom T-shaped locking pin to securely hold various end-effector attachments. Download this model to:

Run a Tolerance Test: See how your 3D printer handles precision engineering clearances (0.2-0.3 mm).

Feel the Mechanics: When printed correctly, the key locks into the grooves with a satisfying, tactile mechanical "click".

Test the Structural Strength: The parts are specifically sliced and oriented so the plastic layers resist bending and torsion, guaranteeing maximum strength.

3D printing settings

🖨️ Print Settings
Material: PETG (Recommended), PLA, or ABS.

Perimeters/Walls: 4 to 6 walls for maximum strength.

Layer Height: 0.2 mm.

🖨️ Printing Guide (Orientation is Critical!)
Part 1: 8_Top_pr (Lock Mount / Wrist)

Orientation: Flat on the side cheek — follow the arrow indicator on the model! This guarantees perfect concentricity for the holes and a clean internal lock profile without warping.

Supports: Enable supports ONLY between the two "ears". Use a dense Support Interface (Support Roof at 80-100%) for a clean surface. Note: Absolutely no supports are needed inside the actual locking mechanism!

Part 2: 9_keypin_pr (T-Lock Pin)

Orientation: Strictly horizontal (resting flat like a "T" on the bed). This is mandatory to ensure the part doesn't snap under torsional stress when twisting the lock.

Supports: Tree Supports under the round shaft.

Strength: Use 100% infill or max out the perimeters (8-10 walls) to make the key practically solid. A Brim is highly recommended to prevent bed detachment.

💡 Engineering Assembly Tip:
Right off the build plate, the mechanism might feel a bit tight. Apply a tiny drop of silicone lubricant to the locking lugs of the T-key and twist it inside the mount 10-15 times. The plastic will break in perfectly to the internal grooves!
