Giant Cobra! : 144:1 scale!
My 4th Cobra - check my earlier post for 75%, 100% and 150% scale prints.
This one is 422% scale, to get the widest length over 30cm, which is 144 scale of the 'real thing'
As you can probably tell, I had to split both the body and engines (not shown) into two prints each, so that they would fit on my bed. In total this took over 40 hours for a .2mm print with 10% infil
Unfortunately, even at this scale, the engine flaps are a bit of an issue - after you remove the support there is barely any material to hold the flap to the body - prepare the superglue! If you plan this print, consider adding extra support to the engine flap model before you start.
