These coal loads have been generated using the coal load generator in OpenSCAD loaded by Les Coombes, many thanks to him for making it available. I have used this to create some loads of the right size for the 1923 RCH mineral wagon, and also created a base to set the coal load at a suitable height. As the coal load generator is quite slow to run (on my laptop anyway) these models may help save time for others.
These loads and the base have been sized to fit my design of RCH wagon, they are quite close fitting so may require modification to fit other RCH wagons. Note I have also uploaded another, smaller design sized for the Accucraft version of this wagon.
The coal loads can be printed in black filament which looks quite realistic for coal - to my eyes.
The coal loads are very slow to print because of their random, multi-faceted nature. I also have versions of the same files fused to the base which have to be printed with a lot of supports and takes 12-13 hours to print on a CR10, but creates a secure coal load which is easy to fit into a wagon and can still be removed. I will try and upload these as well.
