WDLR C Class Wagon Removeable sides

This thing is a remix for the sides, ends and underframe to permit the removal of the sides and ends on the 'WDLR C class wagon with removeable sides' by Bblr.
All other parts are as per the original by Bblr and can be found here: https://www.thingiverse.com/thing:4915066

I have now printed these parts, photos now included. All the parts printed ok flat on the build plate, the stanchion ends were supported,
