UV3XL- Ultraview torque Ring

Here is a simple torque ring that i built to replace the o-rings in a ultraview XL cartiridge- I will update the file with a wider ring version as well. I printed x2 of these and replaced the front and back orings in my scope housing. You will need both if you remove both o-rings- These lock the cartridge into the housing (The gap allows easier instalation)
