Given the parametric power of Fusion360, it would be awesome if it could export scripts which would allow parametric designs to be used on the Thingiverse/Makerbot Customizer. I'm not sure how big of a leap this would be to implement, or what the demand is, but I think it would be fantastic.
Examble: I have a design made in Fusion360 on thingiverse.com right now, that simply has a hole for a wooden dowel to be added. It would be awesome if I could upload it as a customizer and allow people to input their own dowel diameter. It would be a huge undertaking to convert my object into openSCAD code manually...
More and more customizers are being available online, and it really makes sense for the 3d hobby community.
