Double Pillared Incline N Gauge Radius1&2

I now have a space for a layout so back to deg railway models. Happy days!

This is part of a set for a double track viaduct and double track incline. I have designed it for standard (Peco) radius1&2 which are 228mm and 263.5mm respectively. The 5% incline is modelled in 8 parts of 22.5degs each, but would recommend ing as many as you can in your slicer of choice. Overall size is 575mm x 413mm x 59mm including approach straight.

This is an pillared version which is ideal for hiding s. The pillars are a bit sneaky and house the next piece in the model. to reverse it in your designer/slicer if you need a counter-clockwise incline.

There are 3 versions, this one, an arched and non-arched version.

I've included a datasheet file and included in 3D printing details.

I've added a few more images and another STL. I finally got round to adding a cork bed followed by a grit ballast sheet. The STL is a bracket for securing the track with a 10x2mm csk screw. Just needs a little weathering now.

Update - the 180deg Incline model is approx 5% and when ed to the viaduct creates a sudden change of slope from 5% to 0%. This can cause derailments. I have added a mod that graduates from the slope to the level viaduct.

D180IP_8of8b - this has a smoother transition from 5%.

I've included 4 other top sections in the viaduct model. These are plain and arched 120mm straight, and plain and arched 22.5deg curve.

Inside Track = Peco ST12 Radius1 228mm
Circumference = 1432mm
180 degree turn = 716mm
Lowest point = 6mm
Highest point = 44mm
Total Rise = 38mm
Gradient = 38mm / 716mm = 5.3%

Outside Track = Peco ST15 Radius2 263mm
Circumference = 1652mm
180 degree turn = 826mm
Lowest point = 6mm
Highest point = 44mm
Total Rise = 38mm
Gradient = 38mm / 826mm = 4.6%

Its designed for N Gauge, but in theory could be scaled up if you have print capacity:-
N Gauge to HO Gauge = length * 148 / 87, same for height and width
N Gauge to OO Gauge = length * 148 / 76, same for height and width

Double check any slicer repairs. Flashprint slicer offers to 'repair' many of these STLs and removes chunks as a result.

Ideas:-
+ If your printer has the capacity then consider ing 2 or more parts in your slicer software before printing. I managed to print a double with overall length of 204mm on a Creator Pro.

• All the parts, excluding the approach, of this model could be printed with zero bottom layers which will save time and material. I would go with minimum 15% hexagon fill if you choose this option.

• Glueing pieces together is fairly easy until you get to the last 2 halves. Check out images for a method to hold parts together while the glue dries.
