I need someone to translate a set of measurements and photos of a prototype bridge into CAD/CAM files that will guide my 3D printer (or someone else's printer, if I end up jobbing the printing out). The project: I am scratch-building a working model of the Cambridge Creek bridge (a fixed trunnion bascule bridge, for the detail oriented!) for the RFC train garden in my hometown on Maryland's Eastern Shore: ![](https://uniim1.shutterfly.com/render/00-k5_WS7Zx7_tfFuOPPIOajmdaStQsEsxpQuitV77CFvRXlbK2tcP82ODR3PwSUVmqqCe7ffHDJpwno-pEcjtJnw?cn=THISLIFE&res=medium&ts=1722015690) I'm well into fabricating the bases and lifting sections, and have sourced traffic control items to use at each end, and the bridge lights, but I've been a bit stumped by the concrete railings. The railing components appear to be modular, with three different shapes, each with a fair amount of detail cast in. The first has open, arched spaces under the rail: ![](https://uniim1.shutterfly.com/render/00-k5_WS7Zx7_tfFuOPPIOajmdaStQsEsxpQuitV77CFvTVEekFetxprLyyEjwBNsdTaAUrgnwgvQnZ_1RWb7NZPA?cn=THISLIFE&res=medium&ts=1722015690) The second (to the right below) is similar but solid below the railing: ![](https://uniim1.shutterfly.com/render/00-k5_WS7Zx7_tfFuOPPIOajmdaStQsEsxpQuitV77CFvQVTH5p-zqjASSAQh8Km85UKwg5ydwHipy3aIZBf9dNYQ?cn=THISLIFE&res=medium&ts=1722015690) The third is also solid, with bump-outs at each end: ![](https://uniim1.shutterfly.com/render/00-k5_WS7Zx7_tfFuOPPIOajmdaStQsEsxpQuitV77CFvTVEekFetxprLyyEjwBNsdT4xJ2Twu75QF_jizMkB1ZdA?cn=THISLIFE&res=medium&ts=1722015690) ![](https://uniim1.shutterfly.com/render/00-k5_WS7Zx7_tfFuOPPIOajmdaStQsEsxpQuitV77CFvRaVmiVe-XGq9PTerUyVMHiKwg5ydwHipy3aIZBf9dNYQ?cn=THISLIFE&res=medium&ts=1722015690) Rather than tediously trying to model all this in basswood and/or create molds from which to repeatedly making castings, my hope is that someone can take these and other photos and measurements and translate them into 3D files, which I can then use to guide my simple filament printer. I don't have an endless budget, but I should be able to compensate you modestly for your effort. Anyone interested?

Beyond my skills. I might suggest looking on websites such as thingiverse.com to see what's there and maybe you can reach out to some of the people there to see if they can assist.

Thanks, Adam, I'll try that next. I already posted on the three train forums in which I participate, so we'll see what surfaces closer to home. ISTM the shapes involved are fairly ordinary, but I have *no* skills in using the software needed to stitch it all together, and enough irons already in the fire I'm loathe to fall into another rabbit hole!

IF you can navigate the Shapeways search function, which is no small feat, you might find bridge/highway components in another scale that can be scaled up or down for your purposes. Not cheap option, probably, depending on how you value your own scratch building time.

Sorry, I am even more useless than normal for your task. However Sean of Sean's Trains on YouTube may be able to point you in the right direction. Drop him a line. However if you need someone to consume a large Dairy Queen chocolate cone on Rte 50 West bound, I am your man!
