    Beats the Stock Extruder Review by Bill
    I have a Makerfarm 8" Prusa i3v, from a few years ago with a Hexagon hot end.

    I'm really enjoying this extruder. I've used the stock extruder for well over a year, and while it worked pretty well, loading and unloading filament was difficult.

    The mounting bracket sold by Makerfarm was well worth the few bucks in terms of time and effort. I transferred the hardware over from the old mount and had a few screws left over.

    I can't say I had an easy install, but Colin set me straight over email. Power down before plugging in the motor (or when you reverse the connection, if necessary) and be sure to get the polarity right on the fan.

    As for the burned out fan, the replacement is an expensive laptop fan, so I opted to mod a 40mm fan and its working great. However, I needed to create a shroud for the hot end. I'm using the Hex extruder, and the heating element wouldn't heat up sufficiently due to the cooling fan. A piece of card stock placed between the heatsink and the heater deflects the air away from the heater, and allows it to quickly get up to temp. It seems to be working great -- consistent extrusion, same temperature setting from my last setup and not a single jam in 20 hours of printing.

    I'm pretty darn satisfied!
