Some more updated hubs

Added two spoke from six spoke 12 degrees and four spoke from six spoke 12 degrees. Someone asked where to get DesignSpark software, here's the link:

The software can be set for metric or inches.
I don't have a 3D printer yet, as I'm still saving up for one. So I haven't printed any of hubs.
