I have two kits by the same "maker" both in 1/350 the DKM Roon (What may have been German ship) and the Sverdlov both are absolutely gorgeous kits and really simple to build. The cross "beams are a product of the 3d printing they can stay where they are. The full hull is in two pieces divided pretty much halfway, The lip that you see on the male end fits quite nicely and makes a firm connection, on my Sverdlov there is a very slight gap between the two on my Roon there is no gap it almost didn't need superglue to hold them in place it was that tight. I am about to order the 1/350 Russian cruiser Oleg
