Ramps Mount - Kossel Mini (4mm gap)

I needed to print a mount for my ramps electronics, and i found this ( https://www.thingiverse.com/thing:1282757 ) nice sliding mount ... but my printer's aluminum extrusion gap was 2mm shorter.
Once I had to customize it for my unbranded Mini Kossel kit, I've changed a little bit to fit my needs.

The cover is not finished yet. The current design will fit the cable chain ( https://www.thingiverse.com/thing:1078216
) when it's done.

I uploaded one link of the chain that will fit.
