Re: a 3d printer printed sundial
Simon Fantastic - I wondered who would be first with this technology! Interestingly, there is a €650 hobby build-your-own 3D printer coming on the market from Belgium : working area 20cm*20cm*20cm. Complete with free driver software (but I think you need to be able to make the 3D model first in a package such as Blender - also free). You can find it by goggling Velleman K8200. With difficulty, I am trying to find the financial justification for that kind of expenditure….. The aim would be to print a miniature one of those magical multifaceted Scottish dials of the 17th C.

Re: a 3d printer printed sundial
I wrote several scripts for Blender (free 3d modelling software). The objects I created were 2d in the Blender 3d world, so while I can export them to .STL files, they are not visible in an STL viewer, nor in TurboCAD. The scripts are in Python and are on my web site (www.illustratingshadows.com) page (stats-Blender.html), if anyone wants to tinker with them. While Blender was the inspiration for using the 3d printer, I opted for TurboCAD because it was easier to add text in 3d form, and to use other such tools. Also, the low end TurboCAD DeLuxe supports .STL files, and is around $130 which is very reasonable for such a full featured CAD system. Scripting in TurboCAD is only supported in TurboCAD Professional, uses VBS among other languages, however execution is slow. While I like FreeCAD a lot, and NanoCAD also, both of which are free CAD systems, neither supports .STL files (yet).
