Hi all,

I just managed it, and finished an eleven year old project.
Now there is nothing left in my way building a dump-car frame from either cardboard or sheet brass - the only three parts that couldn't be fairly represented by multiple layers can now be 3D printed: Wheels, axleboxes, and coupler-bolts.

The story about the history of the two latest parts is told in a few words in my blog:  http://ralf-mit-f.com/3d_get-it-printed - as usual in English and German.

Fully-3-dimensional Regards,
ralF with F..eldbahn
