This is a stackable Lego compatible bridge Pier thats meant to go under the Lanes of a carrrera digital 1/32. For the Lego bricks to fit (in my case because i had a little elephant foot) you need to nearly melt the Printed ,,Bricks'' on the side of the Part. Then press a 2x4 Stone in it to make the fit perfect. Under the Lanes there is a cross wich i have modeled a negativ of into the Part. From my knowledge curves, and straights have this cross on them.
