Super Cool BTT Manta M8P 5015 Fan Channel

A remix of @Anollya_1115736 M8P Fan duct but with @SimplifiedLife's Vents from his Octopus Duct, I increased the walls to be thicker on top and sides for it to be more sturdy (the original cracked for me, and a optional bracket to use if you don't want to put heatsets in your fan, or don't want a m3 hex nut accidentally dropping on your MCU while your printer is going BRRRRRRRR


BOM
2x m3x8 SHCS (use the ones your already using to mount the Manta M8P to the DIN Rail Mount) to screw the duct onto the m8p and onto the DIN Rail

2x m3x20 BHCS 
or 
2x m3x25 BHCS
2x m3x4x5 Brass Heat Inserts (Voron BOM)
or
2x m3x20~25ish BHCS
2x m3 hex nuts 

Instructions
You have 3 options Method 1 and 2 are preferred: 
Method 1 to use the heatset bracket and have the 5015 fan sandwich between the bracket and the fan duct using heatsets in the bracket 

or

Method 2 You can also put 2 heatset inserts in the bottom of the 5015 fan itself and bypass the bracket in total, screwing directly from the duct into the heatsets in the fan

or

Method 3 Similar to the heatsets, but using m3 nuts on the bottom side of the fan, and use those to squish the fan against the duct with m3 screws going through the fan holes completely (suggest using loctite or similar so your hex nut doesn't accidentally drop on your MCU while its on and end up with magic smoke coming out of your electronics bay) 


Printing 
Print flat sides down for both parts.

Anollya's Base, with SimplifiedLife's Vents
thicker walls, added additional optional heatset bracket to hold the 5015
