Thanks Ed, with a little bit of extras and some weathering, it will look good as a small lumber tractor.

My pleasure!

I was busy trying to find funny inappropriate things to print in low-res and these got in my way. Figured someone should get some use out of the thing preventing me from finding the triceracocks.

What did you scale them too? The originals from the description are 1/100, but when I scaled them 62% they still look wrong.

  I haven't measured any of them yet, so I don't know how close they are. These are scaled to 55% and they look very close.

these would fill in rather well for my old D73T, closest would be the ones in the older photo, but only a nit picker could tell the differences, lol

I was playing with this dozer and I made a small scaling error.  Ended up printing at 1/320 scale.




The little hook on the bottom printed just fine at that scale.  I broke the one track and the one platform corner when taking the supports off.  I need to be more careful with the next one.


And the holes in the draw bar printed as through holes too.


N scale D7 with "mini D"!


Every detail in the bigger one is right there on the smaller one.  This mini 8k is impressive.

Use the mini as a yard sign for a construction company or heavy equipment sales company
