MOPB - TRAIN TUNNEL (LEGO COMPATIBLE)

myminifactory

Here are several LEGO-compatible train tunnel entrances. For roads, check out this tunnel here: https://www.thingiverse.com/thing:3490244The surface features a familiar stone structure or is flat and the columns consist of three 4x2x3 blocks. The bottom has extra reinforcements for added stability during printing.The STL files always specify the number of tracks, the space between them and the edge distance. A 2x8-8-4, for example, has two tracks with eight studs each, an eight-stud gap in between and four studs on either side, making it a 32-stud tunnel. With two columns at two studs each, the total outside width is 36 studs. The STL files I've uploaded should cover most common uses since they were designed using OpenScad and can be customized. Just get in touch if you need different dimensions.Comments are welcome, especially about how well the bricks fit in your prints!
