So.. when your kids ask you for a "like no other" train and you happen to own 3D printer with bed size 15x15 cm or more, you...
Have everything to successfully fulfill their request! :)
It's just as easy as printing out of ABS or PLA set of objects most of which have not more than 3 cm height.
(Ok, you'll need 2 pcs 1.5mm bicycle spokes, some 50 cm of 3mm printing filament, the same amount of 1.75mm filament and a Super Glue or acetone based glue). Average skills in building classic plastic models of planes etc. would be helpfull..
Please be carefull these materials/objects can be harmfull and even cause fire at your home. Always keep to the safety instructions provided with the materials used.

The model to be printed is available from now on for free download just here in this instructable (personal use only).

If you really like it - you can also buy it - I'm selling it in the following shops:

I wanted to make this instructable least complicated possible. I believe words would be highly insufficient. Pictures are allways better for describing the assembly process..

Have fun and good luck!

PS1. Please let me know If you have any suggestions and remarks regarding this project..

PS2. You could scale it down for "O" gauge (32mm) the scaling factor is: 0.847 - it will fit the track, but will not reflect any established model railroading scale.

PS.3 The latest generation of my collection has a radio-controlled version of the locomotive. Visit www.euroreprap.eu for more information.
