My scopes end cap has a 45mm inner diameter inside a part thats threaded on so this is made to push fit in that space. Theres no threads on this design.
I have printed in PLA+ which probably isnt ideal. Its made for airsoft so I imagine one hit would break it but its a quick and easy print.
I have included the F360 files if you need slightly different dimensions.
