he man effe een vraagje ik wil hem graag zo groot mogelijk printen op mijn cr-10s en daarvoor wilde ik hem in 4 stukken hakken maar elke keer als ik dat deden de 4 stukken raar, er ontbraken dingen en zo. kun jij dat fiksen?

I can't see the dutch mountains on this model, the nits are singing about... ;-)

Warning to all! I was printing this in quite a big format. Turns out it went wrong, some lever 2 or 3 regions the base didn't print, so it tried to bridge that in some layers up. I checked in Cura - that was fine, but in S3D it sliced wrong. Fixed the file with Netfabb and now it's slicing good! Will share the print once it finishes!

oke dus ik weet dat het in het echt zo is maar onderin bij het eiland zit het los kan dit vast?

Kan wel, dan moet je wat verbindingen maken. Kan misschien wel gewoon in Sketchup ofzo?

Had dit model een tijd geleden al eens gezien en toen geprint in 1 kleur (oranje :)). Heb nu een printer waarbij ik in de software al aan kan geven wanneer de volgende kleur moet starten dus zal eens zo in blauw en wit of groen en blauw printen.
Top ook dat je een uitgebreide omschrijving hebt voor gebruik op school. Dat is precies wat ik nodig heb voor de scholen die we bezoeken!

Cool! Ben benieuwd naar het resultaat, en hoe de reacties op de scholen zijn!

since when do the Netherlands have heights (other than vaalserberg and the dunes)

Since... Forever?

What would be the curvature on this model if you would want to map it on a globe?

The curvature of every country would be roughly the same, since it has the radius of the earth; about 6,372 km. The Netherlands is about 310km at its widest, north to south from Rottumerplaat to Vaals. The calculations here are simple Pythagoras, although hard to explain in text; but according to my quick & dirty maths, this means that when you isolate the Netherlands from a globe and put it on a flat surface, it would be about 2km higher in the middle.

Translated to the size of an average printer, let's say 200mm at its widest, this would mean the middle is about 1.3 millimeters higher than Vaals/Rottummerplaat. With this size, the radius of the resulting globe would be about 4,100mm or 4.1 meters.

Does this answer your question? These are all rough estimations, but it gives an idea of scale!

That's exactly what I was wondering, thanks!

So the curvature of the Netherlands is barely noticeable on a model like this. Just as the real hight differences are if you transpose them to a model of this size.

Exactly - the country is much too small compared to the entire earth. And even England or France would only get an elevation of 3 to 4mm. For real results, take a stretched country like Chile (18mm), or just a vast one like Russia (16mm).
