hcmaker 7 cable chain for heated bed

This is an upgrade for HCMaker 7 (Adimlab Gantry)
It also work for any cable with JST VHR 6pins connector.
This is heated bed connector enforcement for cable chain on Y-axis.
You need 2pcs self-tapping screw 2,2x6,5mm
and 17 (or more) cable chain links https://www.thingiverse.com/thing:2757810
Better to use equal amount of top and bottom links.
I've screwed last chain link to 2020 profile under printer with 1pcs M3x8mm screw and printed t-nut. Like https://www.thingiverse.com/thing:3050607

Work in progress: last link lose it's form when screwed. So better to redesign it....but later.
