N: IronMink's ConFlat L & L-type-container, 1-148

If you are looking for British railway models for 3D-printing, IronMink is probably the designer of first choice. In any case, I admire his work immensely:

IronMink designs for OO but publish everything in 1:1 scale. 
But the issue with rolling stock is always, that scaling up or down is even not half the battle. You need to adjust to available wheels and couplings, that are quite different in each gauge. Beside this scaling down makes parts of the design much too fragile for printing, so you have to strengthen things, if possible, without disturbing the general impression of the model. Then the are questions to get the thing running well. In n-scale weight is always an issue, as wagons, that are too light will derail at any possible place.

One of Ironmink’s nice designs is a conflat L-wagon with L-type container. These containers were used by British railways to transport bulk cargo. 
Since I like to create my own wagons for my containers sooner or later, I took this one to practise the techniques of how to design rolling stock in n scale. It took quite a long time to get it running. Beside strengthening it turned out I hade to widen the complete under carriage. Much time I needed to find the right size and positions for bearing to adjust to the wheels. I also experimented with two couplings (from Peco and Dapol). And I found a way to get weight into the wagon, invisible, even in case the conflat runs without containers.

So, there are two variants now available, each for a conflat L with sides or without:

A) Version with Peho-busches, N-Train-wheels and Dapol-couplers:

B) Version without bushes, Atlas wheels and Peco-couplers:

Atlas 22020 33”-metal wheels (14.1mm/5.1mm):

Peco NR-102 -Coupling (pocket not used):

Both versions work quite well. Wagons and Containers are designed for resin printing. To solve weight issue, you may print weights in FDM using metal filles PLA – it’s really great stuff with a density of 4kg/m³:

I printed with 0.4mm-nozzle, based on recommended settings, wasn’t much sophisticated.
Of course you may also glue weight into the containers, but weight at lower points are always better.

Decals for DIY-printings are availible in PDF-file, including instruction and source for white toner. 

I hope you enjoy this remix and find a use for running it on your layout. If so, please give IronMink a like. Without his work, this remix would not exist.
