This is a gravy boat train that is compatible with Thomas and Friends trains and tracks.
Supplies
The parts that are not 3D printed are tacks and magnets for the linking system and some kind of 2mm metal rod for the axle. This could be a nail or any metal rod. A mallet would be useful for friction fitting parts and a hot glue gun if anything is too loose.
Print the Parts
The sizes of holes on the printed parts should work well, but if you print it out and some parts are too tight you could drill them out or use hot glue. If you want a perfect friction fit you can play around with horizontal expansion settings should the models not work for you.
There is a separate gravy piece you can print in brown if you want. It is made to be removeable but you can also hot glue it in.
The models may need to be oriented properly when you import them into the slicer. For the wheels I printed them with the big flat side facing down and used supports for it. I would recommend 0.16mm to 0.2mm gap between the top of the supports and the part it's supporting.
Put the Gravy Boat on the Train Body
The connector pegs connect the gravy boat to the train body. These don't need to be super tight because you can also hot glue it.
Put the Wheels On
Put the wheels on to test the tightness first and the spacing between the wheels and the train body. Make sure the wheels have a tight enough fit that it won't come loose. Once you confirm tightness of the wheels on the axle and spacing between the wheels and the train you can put it on the train.
Put the Tacks and Magnets On
Align the tacks and magnets and use a mallet to tap them in. After this you should be done.
