Issue Fitting MK3S+ Fan Shroud while Upgrading with Kit

Hello,

While going through the MK3S to MK3S+ Upgrade Kit, I ran into this issue while attempting to install the ASA fan shroud included with the kit. I posted a comment in the prusa instructions describing it. 

"When trying to use the shroud provided with the kit, it looks like it is too small for my extruder block? My heater and sensor cables are coming out on the left and I have to adjust the position that my heater sits in the block to clear the cables but, then it seems that the block collides with the printed air dam. Any suggestions? (MK3S, Stock Heat Block)  https://imgur.com/a/lRWr5VZ "

I've attempted to fit this twice now. Both times, it seemed to me that the printed wall on the inside of the shroud touches the side of the heat block before it lines up properly. So, the screw hole on the shroud is off by at least 3mm if I try to fit it like I think it should fit. 

Any suggestions? 

Thanks!

Hi David,
Your heatblock is on Back to Front, the heater should be towards the rear and thermistor towards the front

You heatblock is installed backwards.

The wires should point to the left like yours. But the heater should be at the back and the nozzle at the front (near the fan shroud)

Thanks for the help! You're right, I turned it around and now it fits perfectly. Thanks!

@baklin

Yep, that was my issue. Now that the block is turned around, it fits correctly. Thanks for the reply!
