That looks like a 10,000 piece jig saw, good luck.
That's why i went for the oo works j15. A heavy price but all the work is done.
it might have taken me a couple of years to build that.
but the tender looks good.
OK, i think the green should be closer to the C class 231 at DCDR.
I have added one picture to go on, you can let me know when you need more.
I only have 5 or 6.
Do you print these yourself ? or do shapeways print them ?
Did this happen before ?
If you have the weights on the middle try a bit of heat from a hair dryer or blow heater, but watch it's not too close.
