About this 3D model

Just a part 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/tpmrq7eftsebcnj/track%231.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 >>Please note, this model requires bed size of 7x23 cm >>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 :)
