New hotend support for Anycubic kossel and NF dual hotend . You can find this hotend in https://goo.gl/KK2f8i It works like an Y splitter and you can print in two colors or materials.
I think this is one of the best options for the price and one of the best ways to print in multimaterial with a delta 3d printer.
When printed I attach the original fan with double side tape and it works really well.
I hope it works for you.
Print it in ABS or similar.
