I went with Zennmaster's set up here: http://zennmaster.com/random-things/...nd-basic-setup You can find some discussion on it on the boards here as well: http://3dprintboard.com/showthread.p...s-enhancements

Clough42 has a nice fan shroud as well: http://www.thingiverse.com/thing:351280

Gmay3 has a nice spool holder compared to the stock one too: http://www.thingiverse.com/thing:638906

I haven't seen a nozzle wiper yet, not specifically for the MakerFarm at least. If you haven't done so, I would highly recommend getting a Raspberry Pi and setting up OctoPi/OctoPrint for wireless printing....almost as amazing as auto bed levelling!
