Hello

Nice project! I like it slightly better than the original by jonathanrswift. It needs less space and looks better.

I wonder tho, why did you make the nozzles wider and place them lower? Does it improve cooling performance?

Cheers!

Thanks, actually it is lower because I use silicon sock and with original shroud the sock obstruct air flow. Exhausts are wider and lower becouse I think that the air flow will spreads better below the nozzle and to the front and back sides, so if the print speed is higher, the surface is exposed to the fresh air a little longer. However I did not try simulation it in CFD.
