About this 3D model

This track simply solves problems with closing more complicated loops.. VERY useful.. Compatible with "ERS" of course. To learn about the extremely complicated process of assembly.... take a look at this PDF instruction: https://www.dropbox.com/s/hmm19cf4rx05tk6/track%233A.pdf?dl=0 :) >>This track can be joined with with LEGO 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 (I use metal nail file for finishing places where excessive material remained)
