Well Done.
It's great to see someone making their own wagons rather than just buying off the shelf.
Innovation and experimentation are what make this hobby so much fun, lets face it without them where would we be?
With so many suppliers dropping out of the hobby and the cost of freight/postage, more of us have to resort to our own devices to enjoy this great hobby.
Must admit that this is further strengthening my interest in 3D printing.
Bit better than my first attempt
