Lumia Mount for Motorbikes

This is a phone mount designed to be attached to the steering tube of a sports motorcycle via a anchor bolt (or a rawplug). You will need to get the bolt and one or two 2cm-wide velcro straps to secure the 2 pieces as shown in the image.
You can use the .scad script to generate a mount for your phone: Just measure it at the widest points in all dimensions and execute the script with the numbers. Should work with most Lumia phones.
I tested it with a Lumia 735 (or 730). The .stl files for an iPhone 6 and iPhone 6+ are not tested with an actual phone.
