water stop valve V2 （QDC）

The brand new version of the water stop valve features a smaller size and better performance(quick disconnect). All parts can still be 3D printed without the need for supports.Compatible with bottled water (e.g., C'estbon) threads.
Main body: PETG
Spring: PC
Optional: TPU for AMS for better sealing performance

Important: Print using a smooth plate for better sealing.

If you have H2D model you can try tpu 85A for best sealing.

Update：

3/2  Female connector version updated with a self-locking feature. If the locking/unlocking force is too high, please insert and remove it a few more times to achieve the desired locking force.

3/8  Added replacement parts compatible with soda bottle threads, compatible with both male and female version.

4/29  I fine-tuned the spring and related parts, and now the water flow is smoother. I added a sacrificial printing spring, the first spring always tends to break more easily during printing. Please  use the second one directly,  it is more durable and less likely to break.

8/13  Modified the spring length. Previously, when the spring was compressed to its maximum length, it demanded too much from the material and was prone to damage. This issue has now been fixed by adjusting both the spring and the bottom retaining plate. All other parts remain fully compatible. If you wish to upgrade, you only need to 3D print the parts that were modified in plate 2
