Các bộ phận nâng cấp toa tàu Hornby Mark 2

There are two versions of these coaches, those with bogies that have plastic pivots and those with riveted bogies. Some of the parts are specific to one type of coach, others are generic. 

There are files to:

• Lower the ride height of the coach (specific)

• Add brakes arms to the bogies (specific)

• add vacuum or air brakes, including air reservoir (generic)

• add coach end doors (generic)

• Change the coach body supports so you can dispense with the screws that intrude into the passenger space (generic)

The files are optimised for FDM printers and black PLA filament is recommended as then painting may not be required. Use the highest quality print settings you can - the parts are small and won't take long to print. Some sort of brim is also recommended to stops parts from warping. I would also recommend using the ironing feature. I use PrusaSlicer, which has all these features and is the best slicer, in my experience. Some assembly is required for some of the parts - use superglue.
