this is going to be a scale model of a Vekoma mk 1212 rollercoaster train. I am building it 1:12.5


Some parts need to be fine tuned to fit together. I am going to sand it smooth and paint the parts. Several parts, like the main axle (hoofdas) and the two wheelcarrier parts, need to be glued together, for the finished product. To fit the wheels I smooth out the holes with a 3,5 mm drill.

Now I am working on the passenger harnas, and also the front and the tail off the train.
I intend to build a full train, this means a total of 7 coaches, 3 normal frames (1,2,5) 3 chaindog and anti rollback frames (3,4,6) and an end coach.

Yes it is going to be a big model. (about 1,40 m in length)
Do not yet know if I will display the train in a straight, a corckscrew or a loop.

As you can see, tail and nose are done. Nose 2 goes underneath nose 1 and you will have to adjust the body just a little bit to make it fit.

The restraining harnas is also done. Printed it with exterior support.

I have a problem with your .dwg file.
I used Solidworks and it's not possible to open your files.

Can you export it on .stl?


I need just this files.

Thank u :)

Zeer tof model! Zojuist de bestanden gedownload, wat een details. Ik ga hem zeker printen! Heb je toevallig ook een bestand om track te printen?

de track heb ik laser gesneden. ik heb daar dus geen 3d bestand van.

Oké dan ga ik zelf aan de slag met een oplossing. Ik heb al een flink aantal onderdelen geprint nu. Toevallig is de printer nu bezig met de main body.

Ik mis tot nu toe enkel 1 3D model. En dat zijn de "ringen" (of hoe leg ik het goed uit...) die om de assen gaan bij het aspunt. Heb je die toevallig nog?

ik heb net een bestand toegevoegd maar ik zie het tot nu toe nog niet staan.. als het goed is gaat het om de hoofdas.
ik zal nog eventjes zoeken naar eventuele andere bestanden en deze proberen toe te voegen.
Ik ben benieuwd naar het eind resultaat..

I can upload my track make with solidworks if you want :)

do you have any info on that track?

the track is lasercut. and it is made out off acrilic.

That is correct.. I built this model inspired by the New trains..

This is really amazing!
This is the train of the python isn't it?

The coach was printed without supports.. some treaths wil hang out in the end, but this is easy to remove with some sandpaper.
at the end I smoothed it all with some sprayputty to get a real nice finish..

Did you print the coach with or without supports?

Hello Phoxyboy and CitrixCX,
Thanks for liking my model :)
How to put it together is pretty straight forward work..
All the parts wil almost fit together.. So I used a bit of sandpaper to take off some of the rough texture caused by printing..
For the holes I used a drill so it wil fit and run as wel (wheel e.g.)
For the track.. this is plexiglas tubing wich is available in hardware stores.. the ties however, i lasercutted them out.
Think i stil have the dwg drawing for it.. I will put it in the list..

This is GREAT! Do you have the model for the track, as well?

nice fils!
But i want to make it for my own.
do you have a build instruction for the assemby for the car?

i would love to see that!
