 +The main concern with using a cable chain for the Y-axis is how to make a connection which is both capable of sustaining high currents, can be crimped, and is small to fit into a 3d-printed enclosure.
 +For this, a suitable option would be to use unisolated cable-shoes. These are easy to source and easy to use with a 3d printed mounting base, which functions as a junction box. On the picture below a first prototype can be seen:

 +To protect the open connections, the design was improved, by adding 1mm thick walls around it:

 +With the cover, mounted on the junction box and on the junction box mounted onto the aluminium profile, it looks like the following (click on picture to zoom):

 +At the picture the following are shown: 
 +  - Aluminium Z-profile, 20x20x20, 2mm thickness, 45mm length 
 +  - Cable chain, 10x10xR18 
 +  - JST-XH connector & socket and 2-pin header to connect two sockets with each other 
 +  - Cover, to be printed 
 +  - Junction box, to be printed, with 2x M3 tapered screw, 4x M3 nut, 2x washer, 2x spring washer 
 +  - Final result of (1), including 2x M3 tapered screw (black) and 2x M3 regular screw (to mount Z-profile onto Y-base)
