Stepcraft cablechain modification

I had a Z-stepper wire broken at the connection part down on the left-Y bracket.
So I decided to rewire the whole thing and to install a cablechain.

I reused a cablechain I had (similar to [this one](https://www.banggood.com/10-x-15mm-Plastic-Cable-Drag-Chain-Wire-Carrier-Length-1000mm-With-End-Connectors-For-CNC-p-995512.html?rmmds=search&cur_warehouse=CN))
The cablechain runs on a Alu 20x20 L-profile supported by 2 printed supports ('front support' and 'back support' items). These supports are mounted using one M3 screw and have a tight fit.
I used a 12 wire Lapp-cable with 0,5mm (numbered) wires. 1 to 4 are X-stepper, 5 to 8 are Z-stepper, 9 and 10 are endstop switches for X and Z and 11 and 12 are for the LED-strip.
The cable comes from [Conrad](https://www.conrad.be/p/lappkabel-0026105-geleiderkettingkabel-olflex-fd-classic-810-12-g-050-mm-grijs-per-meter-602996)

I reused the cable protection from the cabling under the bed to the controller board (13mm dia) and installed
