Hi jrathfon, sorry for the delay, I missed the notification. ad 1. Smaller orders cost about $13 to ship to USA. ad 2. Thanks :) ad 3. I think we will add them eventually, still weighing pros and cons. ad 4. What do you mean that it limits you to parallel siding? Thanks for the feedback! Jacek

Just finished a small "system" for the narrow gauge based on the dual gauge turnouts and R24 curves: https://www.trixbrix.eu/en_US/c/Narrow-Gauge/26. Curious what you think :)

@jrathfon As promised, here's the narrow crossing. Still a prototype, not sure if the studs on top are needed or wanted :) Will have the wider curves soon (with holes in the bottom). The originals are R24 (studs between center of the circle and center of rails). Should the bigger R be 40 or rather R36 so there's a space of 6 studs between the rails supports? After that, the dual turnout and then we will add the holes to our regular tracks I guess. The holes make the tracks a bit less rigid, but otherwise they are ok. EDIT: Just saw the other thread, not sure if there's already some conensus on the radii.

I'm working on the narrow crossing, and will try to do the bottom holes in this design first. Hope it prints well despite the reduced contact patch. Anyway, I will have some results in about two weeks - I'm going on vacation leave for a week.

@cameronmiller1988 We are planning on doing this for some time now, we have some promising results but still a lot of work before we are finished, mainly related to the printing difficulties. Which type of tracks would you like to be attachable first? @bartvdpoel Glad you like it, saw the photos :) Would it be ok if I posted your photo on facebook? @jrathfon You're right about the straight tracks. I'll start with the crossing since it's the easiest. The dual guage turnout is a great idea! Guys, thanks for the great feedback, I appreciate it very much!

Glad to hear that Igordost! As far as the narrow gauge 4-wide tracks go, in addition to the narrow adapter, I will design straight tracks and crossings first as soon as I get the original curved tracks from bricklink.

Bart, thanks for your order and for the feedback - I must have messed up the webshop config, will fix :) I'll throw in a few of the narrow adapters that I modeled in the morning. Not thoroughly tested though. This is how they look: https://www.instagram.com/p/BNARS3RjrTj/

It was a bit more than just cutting the middle, but nevertheless here it is, I will print a few in the evening to make sure it fits. Too bad I don't have any 4-wide tracks to ensure it works perfectly with real parts. Are the connections geometrically the same as in the wide tracks? Edit: Just grabbed some straight rails and narrow curved tracks from bricklink to do a proper testing.

Of course. You can send a blank check to http://trixbrix.eu ;) This might be too much of a niche, same as with monorails. Sorry :( Double slip is definitely on our map, quite a challenging part! As for r104 switch, not sure it would fit in the print bed (20x20cm), it's quite a wide curve.

Thanks :) The double crossover was the hardest one to pull off, barely fits on the printer bed. Glad you like it :)

Unfortunately no - this is the compromise we took - no studs on top, and no holes on the bottom. We had prototypes that had the studs, but since the 3d printing has less accuracy (~0.05mm) than the Lego molds, we were afraid that the 3d printed parts could scratch the original bricks. This is the last thing we want of course. We could do the studs, but to be on the safe side, they would be smaller and wouldn't catch the lego bricks placed on the studs as good as the originals. But maybe keeping the bricks on top in a set position would be just enough? Thanks for pointing this out. I'll see if ballasts like this one are achievable. With the holes, it's a different story - mainly related to the production technology. Having the holes, the first printed layers would have a very small surface that sticks to the print bed and causes higher percentage of failed prints due to warping. While 3d printing opens a lot of possibilities, it also has some non-obvious but hard limits.

Thank you Grand Duke. I still have a lot of raw material from that day that shows some details in a more peaceful manner, I'll upload it when I put it together. Actually, to make this video which is just about 2 minutes, we filmed for the whole day. Lots and lots of derails on the grass and gravel ;)

Hello all, I hope this is not seen as too much of a self-promotion. Anyway, I think there might be some interest in the custom tracks, like expressed in the thread about the BrickTracks Kickstarter campaign. For some time now my friend and I are working on various custom tracks and we would love to hear what kind of tracks we are still missing in our collection. I know that 3d printed parts do not have the nice glossy finish of molded parts, but the value comes in the relative ease of adding new parts to the roster, while molding requires high up-front costs. Here's a short video that shows some of the parts that we make: https://www.youtube.com/watch?v=wVN2rIGip40. Best, Jacek

Hello all, My name is Jacek and I am co-creator (with my friend) of custom Lego City Trains tracks, crossings and crossovers. Some time ago I purchased a 3d printer and shortly after it sparked an idea. Would it be possible to print some custom tracks that are not available from Lego or the production stopped some time ago (like the famous 7996 double crossover)? It turned out that it's possible, although requires some considerable amount of work and developing new skills. The results seem very promising - to the point that other AFOLs started asking me to print the parts for them. If you are curious, here's a short video showcasing some of the pars: https://www.youtube.com/watch?v=wVN2rIGip40 I'm very interested in hearing your thoughts - is this something you would use in your layout? And more generally - do you think that custom designed parts are a good addition in the Lego builds and layouts? Perhaps in Technic builds? I know that some fans of Lego don't tolerate parts that don't have the Lego trademark on them - I'm ok with that of course. I hope that I'm not breaking the rules of this forum regarding self-promotion. I'm mainly interested in discussing the ideas, the needs that can't be satisfied by the original Lego parts and that could use some 3d printing help :) With regards, Jacek
