BIQU BX H2 cooled by Opticooler gone MAD

I really love the Opticooler on my Wanaho i3 v2.1 so I thought why can't I use it on my BX? 
So I started to tinker with a remix and found the MAD system. Was a perfect match. 

It's not really in the spirit of the MAD mod.  I changed the base, to be able to use the Opticooler and I added a slot for an connector.

The OptiCooler source can be found here https://www.thingiverse.com/thing:2927210 

• No support is needed for any of the parts.
• PLA works as longs as you don't have the printer in a enclosure. 
• Do not need to turn around the motor(BIQU BX)
• Same as the MAD original you need a extender for the screen. (BIQU BX I used 40mm )
• You need to bend/move the cables and bend the led to fit the inner funnel. 
• Same as the MAD you need heated inserts M3x5.7 

Removable funnels, 
if you don't need cooling just remove the funnels 
If get a bad print the funnels will break off and you will not get a big bal of filament 

Connector:
Add it so it's easier to change the fans if they break down. 
Remove the first layer for the connector channel after print.
