I'm sorry for the confusion, but those files are not meant to be printed separately on their own, they are for multimaterial printing solutions that needs the model separated to assign different extruders for different parts.

The mountain has printed beautifully on an Ender 3 although it did take 34 hours 13 minutes! I'm having trouble with the train which won't lie flat however much I try in Crura using the 'lay flat' option. In the end I've got it to print with supports. One end of the train is 3mm higher than the other. I've downloaded the file several times in case it got corrupted somehow.

Yeah, it could be a bit wider... problem is that the house is located above the tunnel and I didn't want to make a hole into that, but it might still be an option and would make it far easier to wire. I'm glad you managed to wire it anyway, and thanks for the constructive feedback :)

Thank you. Your hint was helpful. I was able to push a thin wire down from above, and use it to pull the light up from below. It was not easy, because the fit was very tight, but it worked.

As a future improvement to your model, you might want to make this inside path a bit wider.

Well what I did was using iron wire, inserted it through the building's window and pushed it through to the base, wrapped it around the LED and pulled it in. I can't say if it will work with LEDs that size though, I used one of these myself:

This looks great with lights inside. I am using https://www.amazon.com/gp/product/B01JT8ZLB6 .

As you note, "there's one building that requires some trickery to wire." This is the house above the tunnel, near the top of the lower stairway. Any suggestions on what trickery to use, so that I can get a light into this house?

Okay, added those files as well. Thanks for the suggestion!

The pole for the lamp is approximately 2.185 mm in diameter. Rather than printing the pole, it would be possible to use a piece of filament (either 1.75 mm or 2.85 mm would be fairly close), and simply place the lamp on top of this, rather than printing the lamp on top of the pole.

How about providing two version of the lamp (without any pole), one with a 1.75 mm hole in the bottom, and one with a 2.85 mm hole in the bottom. This could be printed and mounted on a short piece of filament.

Thanks! I mostly use 3D-Coat and Blender.

Hello, your works are awesome,
Can I know what modeling software you use please ?

Thank you for the information and the link. I kept going to my account and it always took me to a page that took me back to this page. I could not access my order history. I uninstalled and re-downloaded the software I am using and it will now slice with the newly downloaded STL from my orders. Thank you!

Hello @Dan2212002 this is Cults. For your information, when you download a file you can always have access to it in your personal account. You can access to the updated version without paying it again. Every time you need to redownload a file you've downloaded previously, just go here: https://cults3d.com/en/orders.
The file is not corrupt do not worry. Maybe it's because you did not installed yet a software on your computer that allows you to read STL file. I recommend you to download free version of Meshmixer https://www.meshmixer.com/download.html. It can be useful for you and your son.
Have great print!

The file I have downloaded will not slice, I am assuming it is corrupt. Now I will have to pay again to get a new file? This is my sons project.

Really! I can only download this once?

It turns out that I was able to go to My Account, and then to My Orders, and download the updated files again without paying. I didn't realize this previously. But thanks for your prompt reply.

Uh.. I actually wasn't aware it works like that :| I e-mailed the files for the lamp posts to you now.

How can I get the new files without paying again? My email is herbw at wiskit.com.

Okay yeah, I've been worried about the lamp posts and now had one break a bit on my second print. First I thought they'd be fine since they printed perfectly on the first print that I even scaled down, but now I'm that sure. So I decided to make them thicker and release it as new file, and also added separate files for the lamp posts if you want to try repairing it with glue, like you said. Sorry for the oversight.

I printed this using PLA on my Ultimaker, and it mostly came out very nice. But only one of the lamp posts printed correctly. The others just printed a tangle of filament. Probably if I break them off, nobody will notice, but I'm wondering if anyone had more success with the lamp posts than I did. I'm also wondering whether I could somehow print them in separate pieces and attach them with glue.

Cults is not accepting my payment, I get to the pay button and it errors out!

estupenda

Estupenda

Oh looks like I forgot to mention it: No supports required.

Also interested on knowing if it requires support to print. I just bought it but I don't want to print it without knowing.

What is the size of this model? Does it require support to print?

Awesome design and print! Congrats again Kijai !
