In preparation for SheppArton Festival we have decided to print our own luggage tags as well as other specific items for the event.
This leads us to some rather technical problems of working out scale and ensuring the meshes are printable. However there is a (free) application (netfabb) to do this for us, as outlined by ponoko during the 3D printing forum last week.
Through experience I have found that exporting stls from netfabb and then trying to print using replicatorg does not produce a great print, in fact it seems to be rather messy. My suggestion is to check it with netfabb but to fix it and export it from an application like blender.
We are also hoping to add mood lighting to our printer. Which should not only be useful but also pretty.
