3B Train is a site dedicated to providing 3D models of trains in the
"B train" (Bトレイン) format pioneered by Bandai

We design 3D models of real Japanese trains in this shortened length. You can print the models locally by downloading the 3D file!

By the end of 2018, Bandai decided to reduce the number of new products. 3B Train seeks to fill this gap by providing new models that you can easily print to keep the B train world growing!

3B Train models are accurate, easy and fun!

We make extensive research into the design and specifications of the real train in order to deliver the highest quality rendition. The train's original features are reproduced in accuracy greater than 3D printing capabilities while retaining printer compatibility. The iconic shapes of B Trains are faithfully reproduced in 6cm length. 

Each model includes a PDF with detailed and easy to follow instructions that go over the entire process of painting the printed model, placing stickers and completing details on the model trains. Different models offer varying difficulties to allow anyone to create a 3B Train model!

3B Train models are made to be incorporated either onto Bandai's B Train static "NewSG frame" or alternatively on Bandai's N-scale motorized chassis or non-motorized chassis. This means you can run your 3D printed model on anyN-scale electrified track!
