Wanhao bed cable holder

Needed a cable holder for the Wanhao i3 heated bed, since the soldered high-amp wires are under constant moving during the printing....
I use it with my holder for the other side of the cable:

Print slowly, good infill % and use supports.
Use zip tie to fix the cable to the holder.
Bolt is M3, mounted on the existing hole in the heated bed. Don't use bolt that is too long, otherwise it could touch lover plate of the bed!
