Tunnel Liner Concrete Curved FDM HO – 4001FH


The FDM Curved Concrete Tunnel Liners are 3D printed in PLA or PETG using the FDM process. Wall thickness is 2mm. They extend 30′ (about 4″) into the tunnel and are curved to your specs. These liners flare out by 10mm to ensure clearance of large equipment.  Liners integrate with ZYX Creative Tunnel Portals. Also available in O, N and Z scales. (please contact the Custom Shop for this). Add liner extensions to make it longer (extensions sold separately). Curved liners are custom made to fit your curve radius. Specify radius at checkout. Liners are sold undecorated. Primer recommended. Select your direction of curve below and specify radius at check out. Direction of curve is referenced as if you are driving into the tunnel. Products are made to order. For your existing tunnels, a custom curved liner may be necessary if the exact radius is unknown. Please contact the Custom Shop for details.
