Hotend open support for double 30mm fans

Just a way to support two 30mm fans on double hotends without limiting to the type of hotends (should work for most types). You should use BIG zip ties in order to fix it.

It is open, meaning it does not enclose the hotends for better ventilation, but depending on the design of your printer that could also mean that it throws a lot of air on an ABS print, which is undesirable for it might cause warp.
