Support for Roswheel bike "Phone Frame Bag"

I love my Roswheel phone frame bag - it allows be to navigate using my smartphone. But it tends to flop off to one side of the frame tube or the other.
So I designed this little support bracket - simply use a jubilee clip to hold it to the frame and the bag is beautifully held level on the platform's 'wings'.
This was my first ever object designed in OpenSCAD and I got it printed and posted back to me by admg consulting through 3D HUBS in 3 days for only £4.84 - I was amazed and very happy!
