Redesign of a chain tractor created by Hagen Wolleb (Haggy_23@thingiverse) for use in model railroad scale.

For a low loader-project, I’m working on, I was in search for some cargo.
I found this fantastic chain tractor, that would just fit.
Of course, the original design was made roughly 27-times as big as I would need it and for completely different purpose.
So, I put all parts together and then I had to strengthen the whole thing, partially to redesign, to get it printable in my scale. I added pictures from CAD showing the strengthening in red. Fortunately I could mostly keep the original appearance – I’m happy.
To add more of my own contribution to this remix, I also made a driver and after printing all I found a video of a bulldozer version, so I made this one to (not yet printed).

Hope some other railroad modellers have use for this remix on their own layout or diorama.

Model is sized for British n-scale (1:148). Conversion values:
Continental N-scale, 1:160 -> 92.5%
TT-gauge, 1:120 -> 123%
HO/H0-gauge, 1:87 -> 170%
OO/00-gauge, 1:76 -> 195%
S-gauge, 1:64 -> 231%
O-gauge, 1:48 -> 308%

I added supported STL’s for easier handling, although printing is quite strait forward.
