1 It does not fit together, at all. If you do not have a dremel tool, good razor saw and files this kit is not for you. If you have not worked with resin kits before and do not have patience skip this one.
The areas in black sharpie on the side panels is material that I had to remove for this kit to begin to fit together.
In this photo you can see the saw being held flush to the side while cutting the excess material away.
Here is a photo from the other angle, you can see that you will be leaving a small amount of resin less than 1/8th inch thick.
Now the sides fit the plastic box and we can get to the gaps that need to be filled.
