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
-Does not block top hole
-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.
