Dual mosfet mount for the Anet A8.

I have a write-up on my blog with links to all the required parts and wiring diagram at: http://moderntoil.com/?p=850


-Doesn't interfere with USB connection
-Mosfet boards mount securely with screws
-Integrated stand-off's
-Does not block top hole
-Minimal size
-Marked "Hotend" and "Bed"

Holes for PCB's are sized for 'small' PC screws (M3 x 1/4). The kind used to mount optical drives in a case. They will self-tap right in easily, and hold the boards snug. Other small screws of similar size would work fine.

The top frame screw hole is oversized slightly to accommodate for irregularities in frame pieces.

Is there a case that can cover this and that main board?

Gonna make a remix with a hole in the middle to save plastic when printing.

An elegant solution that goes a step further with the embossed MOSFET locations.

Very nice.

I ordered fets then found this via blog post about your install. Like the mount. Going to print one. Thanks!!!

Screw size is: M3 x 1/4

Direct link to the cheapest ones I could find on amazon: http://amzn.to/2qxENiQ

I am printing this and will install mosfets soon, what size screws are needed for this?

Many thanks for the mount and the wiring write up! Hope this alleviates my "fire fears"...

are the "ctrl in" connections for the thermisters coming from the hot bed and hot end?

There's a wiring diagram in my blog post:


I just replaced the main board on my Anet A8, not planning on doing that again. I found this mount for dual mosfets, ordered a couple from Amazon.com so I could get them quickly and now they are installed. I will be ordering two more for the HyperCube I am building, don’t want to blow the new RAMPS 1.4 board I will be using with it. Thanks.
