Bit By Bit - H0 railroad building blocks

About the project:

This is a 1:87 (H0) module system based on blocks small enough to be printed within 140x140x140mm. The holes in the blocks can be used to mount tunnels and/or other future implementations.The tunnel sections have support for a 57mm wide track bed and an overhead line (4mm diam.) for pantographs.

All blocks are designed for Roco Code 83 with trackbed.

Design is done with Siemens NX. For printing the parts I'm using Flashforge Finder machines (.gx-files created with Fl
