AD5X Stepper motor fan attachments Remix 2

Modification of fan holder attachment for AD5x by Namida Verasche 

I was wondering if creating lip/seal between fan and back of printer will improve cooling so I modified slightly original model and results are... hard to tell really. Original attachment lowered temperature around stepper motor by around 3-4*C (tested by putting multimeter temp probe inside printer near the motor) With the seal I get also around 3-5*C difference but it jumped above 4 few times so its better I guess? Or its just ambient temperature difference or cheap temperature probe I used?
Overall it is not much of a difference, as due to space between back plate of printer and motor, air is pushed out the same way as it simply hit the flat wall as soon as it enter printer so its not very efficient way to cool anything. But if we take in to the account that this attachment doesn't need any modification of printer it self, you just simply slap it on the back, I will call it a win.

Now if you ask if this remix is better than original... Not really, as difference in temperature not bigger than maybe 5% But it have advantage of being easier to install! As original had to be placed precisely by eye. Here seal will pop inside that stepper motor hole and it will algin it self perfectly :D

As for installation and component needed, its the same as original, so 4010 fan, 5v are cheap on amazon/temu/aliexpress. M3x12 screws to attach fan to model and 8x2mm magnets.

Main model can be printed in any material, I picked orange PLA as it was already in printer.
For seal I recommend using 85A/80A TPU. 95A is tad to rigid but can be used if you dont have 85A. And as seal is small and at high angle I recommend print it suuuper slow, its small so it will not take long even at snail speed.
