Trailer Support Part_2x Holes

--For the Flat deck Tamiya Trailer Part # 56306 --

This is the 2 x whole part (EG: 1 x whole on left and 1 x whole on right). I am making this model but don't want to use my existing trailer. So i copied the internal support parts from the original Tamiya trailer. (Please see photos on where they are).

NOTE: I haven't printed yet so not sure this is 100% correct. 

I hope this helps someone else.

PLEASE NOTE: I don't own the first 2 photos of the actual part on the trailer. I found them on Google
