Anycubic i3 Mega /Mega S Heatbed Cable Chain Mod

before you start you need the following parts

drag chain 7x7 like this LINK
connecting clamp Wago 221 this one LINK
melting thread m3 like this LINK (I recommend the short version)
cable ties like this LINK
3mm drill

INFO
you have to drill 2 holes in the case

Since my i3 is in an enclosure, I didn't want a cable chain that drives out to the rear

so i searched the net for a version that i could use but couldn't find anything so i designed my own version

I deliberately designed 2 holders for the chain to prevent the chain from lifting when the heating bed moves backwards, otherwise the print head could collide with the cable chain

this version works with the original glass bed as well as with an aluminum bed
