The BTT SB2040 has a problem with it overheating and sometimes failing with permanent damage. I saw few other projects for cooling but these were prepared for different fan size so I decided to create mine one for WinSinn Fan which I bought on Amazon → https://www.amazon.com/dp/B08R9JZY2Q?psc=1&ref=ppx_yo2ov_dt_b_product_details
I printed that model using eSun ABS
regular PIF profile
it doesn't require supports but I decided to use organic supports, so bridge is nicer.
The author marked this model as their own original creation.
