I've never used them, but have browse the site before, and it all looks very 'professinal'.

Aside from the STL file what other info should I be prepared to provide? Material? Thank you Just choose a material. PLA should be fine, I found a site that had done practical tests and found that (despite the bulk properties of various materials) when printed ordinary PLA was strongest of all - except for high-end carbon fibre. Obviously a gear is only practical to print with layers horizontal. Ask for decent shell thickness (at least 1.2mm, you could go more) and number of top and bottom layers (I suggest at least 4), and a fill of at least 25%. Neil
