I had built this 3D model of a fairly simple L Bracket. It's small but not ridiculously small. It's a 1" even leg L bracket that's, for the most part, 0.125" thick and it's thinnest area is 0.0625". I tried slicing it with Cura and it looks banged up. The print lines look huge! The leg that's horizontal appears as if it would be printed in one Layer? I tried messing with the settings and can't seem to get anything good out of it.

Is this part to small for my printer? My nozzle is 0.3mm, I have an Alunar m508. It's a Prusa clone. I would be very disappointed if this part is considered to small.
