I felt that Slave 1 (6209) had a lot of wasted space inside, mainly from the missile. Once removed you can really customise the ship nicely.
About this creation
Front view. I have widened the body of the ship, but have not changed the width of the base.
Side on. I have also lengthened the tail somewhat, but it still looks in proportion.
Here it is front-on and viewed from the top. This is my least favourite view as it looks overly chunky, but there wasn't a great deal of choice if I wanted to have a decent interior.
I have modified the cockpit. It no longer rotates for starters, which was a huge waste of space. Boba has all of the flight controls here, a weapon, and can communicate with the command centre that he faces.
The command centre is where the missile used to be, and seats two minifigs. The seats swivel to facilitate communication with the cockpit. There is also a window on the left-hand side through to the sleeping quarters.
The cockpit flips up to access the engine compartment.
The grills can be removed to get to the engine. The technic rod allows the wings to rotate together.
There is a secondary cockpit, facing the other way. A continuation of the glass canopy allows this position to see forward. This has access through to the engine as well.
This position also lifts up to reveal a compartment for tools.
The ladder, stored on the side of the ship, can be placed in several different positions to access the cockpit, command centre, or sleeping quarters.
Sleeping quarters. There is a bed, bed-roll, various screens so the occupant can keep abreast of what is going on, a clip for weapons, and a storage area at the back. A minifig can lie flat in here.
Viewed from the other side, you can see the window through to the command centre.
This hasn't really been modified, although on the other side there is a storage cupboard behind the guns. In addition the cupboards which used to be on the sides of set 6209 are now here, one on each side.
The rear panel lifts up to reveal yet more weaponry
Opposite the sleeping compartment is a missile compartment, bery similar to that on the unmodified ship.
The rear of the ship showing the access ramp, half the hatch to the carbonite storage area, and the blast door.
Here the blast door is half open, and the first half of the access hatch is open. Using two sets of hinges allows is to go past 90 degrees.
Behind the blast door are two more doors which open into the prisoner compartment. You can see some engine vents at the back as well. This compartment will hold two or three minifigs, but isn't very comfortable!
With the doors open, you can see the second part of the hatch....
... which also lifts up to fully access the carbonite storage area.
It just slides in. The base is fully tiled
Showing the prisoner compartment doors open, and the carbonite area closed.
The top of the tail has a hidden storage compartment that flips open. It is currently storing a spare missile, but could be used for anything. A carbonite figure will also fit.
Boba climbs up for a well-deserved rest.
You can see the ladder here.
Here is the ship with all the hatches, compartments and doors open. Pretty much every bit of space has been used for something. Fully loaded it can take five crew (one asleep!), two carbonite figures, and three live prisoners.
