Minor Site Update

We now have an e-commerce plugin handling the layout of our 3D-printed part links, etc.  This should make it somewhat easier for our customers to browse products that are available in multiple configurations while remaining on this site.  Links will take you to the corresponding product listing on Shapeways.com.

An added benefit of having the e-commerce plugin is that it will open up the door for us to add future product offerings as well as new 3D-printed parts.  In the meantime, products can be browsed via the new default shop address:  meatballrocketry.com/shop/.
