BOV/DSV retaining ring lock
This lock can be used to safely secure safety rings on BOV/DSV. It can also be used as a tool to open the safety ring.
The locks come in different lengths to match all ring sizes.
Here we provide drawings and resources for your 3D printing projects. Please note that we cannot take responsibility for the final product or its functionality if you manufacture it yourself.
Instructions for selecting the print size:
- Measure the hole spacing on the ring as shown in the photo (in the photo example, we measured something between 25–26 mm – so I choose the 25.5 mm STL file).
- Print and test how it fits:
- If the ring is too loose, print the smaller STL (25.0 mm).
- If the ring is too tight or doesn’t fit at all, print the larger STL (26.0 mm).
