This 1:50 scale Industrial Construction Set is designed for FDM printing. Download includes “I” Beams, Crossbeams and Connectors.

“I” Beams insert into vertical and horizontal connection points on the connector. Crossbeams attach diagonally to connectors by snapping into the slot above and below the horizontal “I Beam” connection points.

All connectors must be printed in “spiralized” mode in order to have the proper connection openings for “I” Beams. “I” Beams and Crossbeams can be printed in either standard or spiralized mode but will look better and be stronger if printed in spiralized mode..

Terminal Connectors have a flat bottom and are used along with “I” Beams to build the foundation and cap the top. The number in the file name indicated the number of horizontal “I” Beams it connects to. There are two versions of “2 Adjacent” to accommodate the two corner configurations.

Connectors have a built-in raft that can be removed after printing. They have opening at the top and bottom to accommodate two vertical “I” Beams. The number in the file name indicated the number of horizontal “I” Beams it connects to.

The “I” Beam has a built-in raft that can be removed after printing.

The Crossbeams are designed to fit tightly into the connectors. Depending on the material and machine you are using you may need to file or sand the connect surfaces to allow them to snap into the connector more easily.

The model pictured is printed with Protopasta Iron-filled Metal Composite PLA and allowed to rust after printing.
