I just made this (slightly bigger for the MK6 extruder fan) and I noticed something interesting: your pictures show the Z end-stop to be on the other side of the Z motor than on my bot. For me the Z end-stop is right where the fan is, which means that I had to cut off 1/4 inch of the bottom part of the clamp.

Not a problem as there is plenty of strength left. But it's interesting to see that different TOMs have the Z end-stop in different places.

Hello

My TOM were observed.

Wow, amazing.=-O

Your right

The board of the back panel is symmetric.
I seem to have put it inside out.

Thanks for the comment.
I did not notice by oneself.
But I do not have any problem. :)

Argh... I wanted to adjust it for a deeper and wider fan but my Alibre does not open the original file.

(You seem to have used a newer version of the AD_PRT -format.)

is it 40mm between holes on the fan?

I'm designing something with a fan

Hi

The dimensions of the fan 40
± 0.3 × 40 ± 0.3
Between the holes, 32 ± 0.3 × 32 ± 0.3
Please refer to data sheet of the fan.

I also like this because it could easily be modified to be a mount for a fan for the extruder motor. Awesome work!

That sound good. Let's try it.

Neat looking part. What program did you design it in? Can you post the source file?

I'd also love to see the source file!

I'm using domestic free 3DCAD software.

STL export only.

I converted it with a blender from STL.

OK?

calibrating wins indeed but i also like the print :-)

I would encourage. :)

I still like it :)

I'm going to agree with the other comments. This is a nice print for sure and glad you took the time to come up with it. But if you calibrate the stepper to the specs in the wiki it runs MUCH cooler and really shouldn't need a fan.

Again nice print tho this might be able to be used some place else.

This is progress, I'll make a new one. :-D

Have you calibrated the stepper driver using the pots on the board? I found that my Z-Stepper runs so much cooler after doing the calibration. The default configuration is overkill fir the motor and causes it to get very hot ( too hot to touch).

Wow

amp;gt;:o

Z-axis of the REF (V) After checking, 2V was over.
Dropped to 0.62V.
Thank you.

DC Fan holder is not necessary.:'(

It will never hurt to keep the motor cooler. Did you check the current and temperatures of your other motors too?

but it's cute :)
