phone to scope 50mm mounting

Bought a cheap ABS mobile phone case on Ebay, and printed this connector piece.
One side fits on my scope, which is 45mm outer diameter.
I'll glue it to the phone case, so i can look at my phone instead of through the scope when I go out shooting.
Edit: Version 2 includes space to put M4 nuts in, so it can be clamped to the scope. Also adjusted the diameter a bit for better fit.
Put 'BREAK YOURSELF FOOL' embossed text on side for fun ;).
