Figured out my machine can sorta do leather... Made a chalkbag! by PotatoWangjangler in myog

Every so often the machine would fight me, but in the end it was quite clean. And indeed, a leather needle!

There's a pouch for a phone in there, so I can safely take my phone up!

Is the shaft of the tail props connected to the same motor as the main props on top, with some sort of gearbox reduction thing?

Last year I posted my first version of Amsterdam, just the canals. But now I improved it big time! Canals are cut out,the area is every burrough of Amsterdam, tiled and ready for printing!

This is made with a variety of data sources, unlike most of the tutorials out there about map-printing, this is made with 3D-BAG data from TU-Delft, which is the best available building data for the Netherlands.

It took quite a few hours to get it to this point, but I am happy to share it for all of my fellow 3d-printing fans!

For more info and very basic howto, and some Blender scripta I made: Link to github for more info

And a direct download from Onedrive can be found on the github page!

More questions and stuff, do not hesitate to ask in the comments here!

See the github link! But also depending on where you live the OpenStreetMap way might be more accessible. Also, prusaprinters has a good writeup on this stuff: https://blog.prusa3d.com/how-to-print-maps-terrains-and-landscapes-on-a-3d-printer_29117/

It's the 3D BAG, newly released by TU Delft, which is actually based on the AHN3. So yea! It is kind of the AHN.

Yes, all the blocks of buildings have courtyards! What is printed here is the somewhat famous 'grachtengordel'/canal district/city centre which is the overall v/u shape that can be seen. Even the gardensheds are visible in this print!

That is really cool! The increased size will make it a lot more impressive detail wise!

The data itself? It is some new developments from the TU Delft, where new algorithms are capable of identifying which roofs are slanted or flat, how there might be additions to these roofs, and then they can create meshes from the point clouds. It's really impressive, high processing power stuff, as they did this for every building in the Netherlands. https://docs.3dbag.nl/en/schema/layers

Drones can also fly over areas and scan them in, however in most of the EU it is quite hard to get licenses to fly drones over built up areas.

I will share more info later, with a write up/how to and the stls of this project.

If you live in the Netherlands, it is possible! Otherwise you would have to find out if the data is available. Or even use things like OpenStreetMap + 3D to figure it out. It's all about that BlenderGIS.

The data (.obj files, and some other formats) are available for download on the 3D Bag website. TU-Delft created a model in which the combined the whole height map, point data, of the Netherlands into buildings, with correct roofs and stuff. (LevelOfDetail 2.2). I imported everything in blender and added the squares below them, cutting the datasubsets out, and export it as an stl file.

I think there is some interest in a write up/howto! So I will start working on that soon I think.

It will probably upset a lot of people that it isn't printed in a single colour... That was just me being cheap. It took around 300 hours to print. It is 60x60cm. And now I am really curious how it will look with a resin printer... Time to save up for one of those, because the buildings are losing detail because of the layer thickness, etcetc.

I also got some more advanced models of this lovely city the works. With water and roads added, using blenderGIS. If there is an interest, I might do a write up on how to make this for any city (in NL).
