3d Printing designs not printing smoothly

[h2befjon 0]

Hello,

I designed on fusion 360 something to hold my shaving stuff and decided to print it in two parts.

these are the settings I'm using in cura:

I printed the first part and this is how it came out:

What am I doing wrong? I don't seem to have an issue when I print other objects from lets say on thingiverse.

You need a lot more top/bottom layers. you set it to 0.4 with 0.2 layer height. So you only print 2 top layers, thats not enough for a smooth surface, you need minimal 6, so 6 x 0.2 = 1.2 mm top/bottom layers, some people prefer even more....

And check you cooling, I assume you print PLA? set your fans too 100%
