Description
Motivation
When building a temporary model railway bridge or ramp, you need pillars with various sizes.
Using Lego for this purpose did not look too realistic.
For this reason I designed a pluggable model railway pillar system, that allows you to create any pillar height you need.
For a more realistic look of a steel girder bridge, I designed a rail element for the curved Rail-C rail with radius R1 30°.
The elements fit on top of the modular Bridge pillar system and can be connected with snap-in-connectors.
The design leaves enough tolerance for the changing slopes needed for the bridge ramps.
The Märklin Rail-C system is intended to be used with for use with our design.
Printed with prusament PLA (Gentleman's Grey)
To build a complete ramp or bridge with ramps, you need quite a number of pillars and rail elements.
For one complete R1 curved rail support element (multi part) you need to print the following components:
1x H0_Bruecke_R1_30deg_Basis_v02.stl (base element)
(print orientation: upright)
(colour: Gentleman's Grey)
1x H0_Bruecke_R1_30deg_AbdeckGitter_innen_v02.stl (steel-grid inner radius)
(print orientation: top face facing downwards, smooth or satin metal sheet)
(colour: Gentleman's Grey)
1x H0_Bruecke_R1_30deg_AbdeckGitter_aussen_v02.stl (steel-grid outer radius)
(print orientation: top face facing downwards, smooth or satin metal sheet)
(colour: Gentleman's Grey)
2x H0_Bruecke_Verbinder_v01.stl (snap-in-connector)
(print orientation: left or right side)
(colour: Gentleman's Grey)
Assembly
[Steel Girder Bridge Rail Support Element R1 30° complete]
The curved R1 rail support base element is printed as as one part.
Simply place the steel-grid-parts (inner radius+outer radius) in their related positions on the base element and carefully push in the snap hooks.
(the steel-grid parts have a different radius and do only fit in exactly their related position with hooks facing down)
This gives a nice impression of a steel girder bridge construction.
The snap-in-connectors go into the small openings (left+right) at the ends of the rail support element.
The connected rail support elements fit on top of the pillar system.
Play & Enjoy!!!
