All Men Are Boys At Heart: Building A Medium Girder Bridge

I'll try to make a 1:35 scale model of a "Medium Girder Bridge" ( Double-Story )
...That's pretty large,- it results a lenght of > 650mm !
There are a lot of photos but less exactly dimensions.
There are slightly variations too, so I decided to choose just the parts i like and to do them as exactly as possible.

Exactly as possible means:
Always regarding the wall thickness limitations of "WSF" material ( Nylon ).
There is no chance to create a 100% copy of all the details,- some parts must be thickened and moved to be printable, but I try my best.




The first part: The "Junction Panel"
You can see, there are critical wall thicknesses already.

The next parts will be the "End Taper Panel" & "Bankseat Beam"
I hope You'll enjoy the assembling of the parts. I'll update soon with the next parts.

Here we go,- the Girder Bridge "End Taper Panel" & " "Bankseat Beam":





The wall thickness check is ok,- after several attempts...

Keep in mind,- the bridge will be printed in separate parts. ( I say,- it will be fun to use Ø 0,7mm needles as connector pins! )

Wondering if the connection's gonna jam?
No, - it won't jam because all connectors have a 0,1mm gap!


Next parts:
Top Panel & Bottom Panel... stay tuned...

As promised, here the "Top Panel" and the "Bottom Panel" of the Girder Bridge.

The assembly:



Don't care about 3D printability check warnings,- the checks are misunderstanding the assembly and the gaps between the parts etc. .
It's just to show You the parts together.

The production status is now 70%
Next parts: "Deck Unit" & "Ramp" .

"Medium Girder Bridge" part 1-7:
Added the Ramp & ("Sway Braces" with all the same length! )

These are still separate mountable parts.
The parts of the ramp are movable and can adapt to uneven ground.

Next ( final?) step:
The "Deck Unit" and a much better 3D View ( not the ugly one from Shapeways ) ;-)

This is some serious engineering my friend.

Nice work!

Thank You for commenting the work!

Now, I measured the final result of the 1/35 scale bridge length:




Background Info:
It was important that the parts are interchangeable as in the original. ( I hope so )
This means that the parts on the left-hand side also fit on the right-hand side. The "Top panels" can also be mounted rotated by 180°.
It was originally designed so that the bridge can be assembled quickly and easily and consists of as few different parts as possible.

The 3D viewer:
(I hope that Shapeways will also be convinced in 1-2 years that they will integrate a better 3D viewer. )

Enjoy!
