These are N Scale replacement couplers for Rapido style couplings. These are shorter than the standard Rapido couplers by 2mm (0.078”) and can be used to bring rolling stock closer together with out causing buffer lock. Using two together will bring the rolling stock 4mm (0.157”) closer giving the impression of a connected corridor.
This set has 20 short couplers.
The coupler head and tail closely match the Rapido standard and couples smoothly to each other and Rapidio couplers. The new coupler uses the existing spring in the Rapido socket.
The BS&F material does leave a rough finish on the on the sliding face but this does not affect the working of the coupler. If printed in the FD material it will have a smoother finish but will require cleaning and painting.
This particular set was designed for a Graham Fairish HST set but will work with any rolling stock fitted with Rapido couplers .
Other lengths and quantities are available on request.
These have been test printed in BS&F however these are currently unavailable form Shapeways directly at present. Please contact me though the contacts page on my blog site if you would like sets in BS&F.
