3D printing. Don't wait for Geobra to make your dream parts!

Would this help if you can scan those original helmet into 3d models and modify it into the thing you want?? So it must hold firmly on klickies head

Well this model was made under 3D S Max obviously and this is way beyond my skills. Still… we're all experts here, and any of us can tell that the torso is wrong. Try go imagine the part as several basic shapes together (cube, sphere, egg, cylinder, etc...) can you see the difficulty with the torso?
The Jingasa I made isn't printed yet. I need Cheng's expertise first…

@ Cheng: to create helmets, I first had to create a clicky head. To make belts or collars, I will need to make a torso, and THAT is really difficult.

hmmm...its not possible to select/fix the internal diameter of the hair-fitting recess area in the 3-D software?

As for the jingasa, there's no 'correct slope/angle for the conical hats....for versatility (polished ones for ashigaru & unpolished ones for chinese or ming soldiers), I'll say make their apexes at 100 degrees....as for the brim of the jingasa....our klickies have exaggerated large heads so its ok to make them as broad as their shirt-shoulders (any larger, they will start to look like fishermen or paddy planters' straw hats)
...hope the artist of this attachment wont sue me...its just my personal opinion

Thanks Cheng. I'll try to send you a sketch, only I don't know what file format I should use…
I assumed these were made from a single sheet of iron, hammered to shape and riveted, so I drew a thin groove from top to bottom at the back and two rivets/studs to simulate the fold. Is that good?

@Heronimus: I don't know about 3D scanners available for non-professional people. Though my prosthetist does have one. The site where I get the prints from doesn't provide scanning. I understand it would be useful to just scan a part and modify it, but: 1-it would spoil the fun and the feeling of achievement when you receive your own parts, and 2-I don't think Geobra would let this pass…
@Cheng: I managed to get a nice fit of the helmets to a clicky head.

what programm u use for modlling?

[cowabounga]

It's called Tinkercad, it's an online software (meaning you work inside your browser). You have to open a paying account to use it.

Arnaud, maybe they dont use rivets...joints between 2 thin flat sheets could have been made by crimping(?) one edge around the other and leaving the 'roll' on the underside...so all we see from the top could just be a clean 'meeting' line folded downwards. so a shallow line is fine but it might weaken the pvc jingasa...anyway geobra might not bother to cast the joint so maybe you dont even want to have the line lest it looks more un-playmolike
jpeg or jpg files would be the more versatile as an attachment anywhere.
would you use PVC strips like me to simulate the chin-tie?

[tonguello]

Ooooooh! awesome!!
The design is amazing Arnaud! 

Is it easy to sand them off? Ho9w fragile are they?
I can't wait to see them finished!!! 

[cowabounga]

Actually, sanding wasn't very efficient. 
My options are then, either to make the models with another software, or to make a first resin cast, sand it and then another mold…
