About this 3D model

These are just a parts of the 3D printable railroad system "Euroreprap Railroad System" To learn about the optimal printing setup please take a look at this PDF: https://www.dropbox.com/s/krrrd0v1rq2drt6/track%231B%232A.pdf?dl=0 >>There is a possibility of linking together LEGO tracks and my "ERS" type tracks (free inter-connector track model is available). >>No support is needed during printing >>Printers with small bed sizes will do fine (for bed areas below 15x15 cm please contact me first to obtain adequate files set on order) >>No special tools are needed during assembly Various "LEGO type" tracks are available freely for download & printing nowadays.. ...but they appear more difficult to 3D print successfully than my tracks :)
