Cover for Anet V1.0 controller and cover with 40x40mm fan.
Plenty of room for cable dressing.
Just make the cables as in my picture and the cover will snap right on.
I recommend everyone to use the one with 40x40mm fan to not overheat the components on the board.

weird. My 40mm fans don't fit this hole pattern.


hi i woul dlik eto mount a computer fan onto it but for that i woul dneed a CAD file to change it any way this is possible ?

Download and install 123D Design, that is a simple and free drawing software,
I have the original 123D Design file on thingiverse so you can modify it youself to your needs.

What way is your fan ? I can't decide if it's better to blow cool air in or suck hot air out... as for the SD slot, I couldn't insert my sd card to easily so I have ordered one of these, http://www.ebay.co.uk/itm/221780787467?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT hopefully it will do the job just fine :)

Oh, that cable looks great...
The cooling fan should blow air in to the cover, then it circulate better.
I am going to replace my cardreader, it started to spit out my card by it self, i had to remove the eject spring...
i will try to find one that extend a little bit furter out from the controller edge.


I would like to remix your design. If you will you allow.
I will send you back what I have done and obviously I will credit you .

thank you

I have added the 123D Design file for cower w/o fan so you can make you own fan fit

Very cool

Could you share the cad file, in order to apta to an old fan I have.

And also I would like to write in the cover a sort of the board diagram. So in case you need maintenance the cover will help you out.


How you fix the cover?


on the inside of the cover is ridges that goes behind the board, it will snap in place...


And what about the access to micro sd slot and the USB? can you share the picture from above?

Thank you


Thank you for the cover! I have a question, I can't use USB connection to print with CURA, I must use the SD card...How do you do?


Are you a meber if the Anet A8 group on Facebook ? There you can download the driver.zip file from the file tab on top of the group page

OK, thank you, it work on CURA 15.04.6

There is a slot for the memorycard, if the cover is fully in place the cover is flush with the cardreader on inside.
You are able to push the card down with your fingernail so it locks in place, and pops up when you remove it,
I put also a piece of scotch tape on my memorycard so it is easyer to grab when pulling it out.

I recommend everyone to use the one with 40x40mm coolingfan.
Use a 12V fan and steal the 12V power from the 12V supply on controller pcb.
Some of the components might get hot, ecspecially if the drive currents are cranced up.

How do you adjust "crank up" the currents for the steppers?

It depends of the version of the controller you have.
On the oldest versions you had a pot next to each heatsink.
On the later versions you have no adjustment pots at all.
On the latest version you have only one pot for z-axis, it is next to the heatsink for the z-axis stepper driver.

How and were abouts did you steal the power from the controller pcb?
Thanks great job

Best is to take it directly from the PSU, otherwise connect it in the green powerplug together with the wires from PSU
