So I finally ordered the peices in and with only 2 small modifications, it's works wonderfully! The curves are lego but the straight track is 3D printed from 4D-Brix. If anyone knows who sells injection molded straight track for lego narrow gauge layout, please let me know. Also, this layout will be 8 base plates, the peice of ply wood is 20 inches x 40 inches.
