About this model

Just a Cooling Nozzle for the Original Prusa i3 MK3. As you can see in the picture, I tried almost every cooling nozzle design found on Thingiverse, most of them performed worse than the stock nozzle. By iterating, I finally managed to get a SLIGHT improvement over the stock HOT!2 nozzle. It automatically aligns with the hotend, the long hole for the M3 allows lowering or raising the nozzle by 0.5mm. I printed mine in PETG.
