3D model description

This is a large scale project designed originally to replace large O-Scale Truss Bridges on a large scale layout. In it's current size it will function perfectly on any O-scale/similar sized layout. Plenty of examples of the bridge in use can also be found on my site:
https://3dcdesign.com/media/

Currently consisting of 13 separate models. No support material needed to print any of the models technically, though a small amount to support the slide insert on a few pieces is suggested. I took a lot of time to make sure this worked out perfectly for how my father needed for his layout.

It can be scaled to different sizes and still retain its full function. No adhesive or clue is required. All pieces slide and/or snap together. There are separate roof/coverings that allow for full or partial coverage of the bridge all the way across. I designed this specifically to be very user friendly to not only print, but use as well. It's extremely strong, even at just 25% or so infill.

Pieces slide together with some pieces having multiple versions to allow an endless amount of pieces to be added. Currently on our personal layout there are two 4-6ft bridges utilizing these exact models.

Filenames correspond to their function/use. There are a couple side/top pieces to allow for multiple combinations of looks. Jimmy Stars is made in remembrance of my brother and his favorite team the Stealers, which is what the star pattern/name on that particular small model mean.

Please follow up with any comments/issues or potential requests. All those who purchase the bridge in its original form will be supplied any updated models applied to this project free of any additional charge. I make sure to email and keep those updated when changes are requested.

Thanks and enjoy!
