Just wanted to share my modified Orballo Prusa Steel head to allow quick access to Heatsink, Hotend, Thermistor, Pinda, etc. Thanks to Tom114 for his “E3D fan with integrated layer-fan (http://www.thingiverse.com/thing:1746358) by Tom114” I’ve modified this slightly to enable an easier quick release, applied some nut locations for the fan (just heat the nut up and push them into the locations) and a finger lever, again to make the removal easier. I’ve modified the Orballo Stl’s to allow the use of the Fan Cowl. And will be doing this for Original Prusa stl’s as well. Cowl can be used on Anet heads as well if you so wish.
