Anon, I don't know where you got this shitty models from, but both have shit geometry and can't be made with walls easily, they need rework, mainly because of the inside geometry on the exhausts. Now, let me ask you the proper question. Why don't just you print them solid, they are just fucking 3.6 and 5 centimeters big?

I think I explained myself badly, I did print them but the wings and ailerons broke because they are too thin... I meant making all the model 0.3mm or bigger. I got em from a guy that made a mod, he said he printed them in 10cm but I want them for a small scale wargame, that's why they are so little.

The tips of the wings are the most problematic zones. They finish in a bevel and that way the printer cant do it and breaks them.

>small scale wargame
Is it based just on Electrosphere or do you have other Strangereal planes planned?

I've never used a 3d printer but your request sounds as simple as either scaling the model (or parts of the model, which you might have to extrude instead), or changing some sort of setting in the printer software prior to printing

His problem is wings end with an edge, that makes the last 2-3 millimeters of the wing too thin and it brakes. It's an easy fix, split the edge, add some thickness, but the models he posted are fucked up, there are intersecting faces everywhere, it's a mess.
