Summary

Here's a 5015 Adapter for the FLSun SR to install on my effector housing

(It should also work with the stock metal housing)

Added STEP File for standard version

You can mount it in 3 different ways:

• With the 2 fans in the same orientation
  You'll have to print the second support in mirror mode

• With the 2 fans "back to back" (air intake facing the exterior)
• With the 2 fans "face to face" (air intake on the housing side)
  In those 2 cases, just print the same part twice without mirroring the second one

It's better to print it with the backplate against the bed and activate tree supports
I recommend at least 3 layers bottom and top, 3 walls and 30% infill
