My first ever semi-useful 3D object designed and printed from scratch. The concept works -- but my top layer comes out horrible... . Any advice to fix this? Print settings: 210 degrees, 0,4mm width, 0,16mm height, ironing on (10%), top layer: 1 Filament: Real - Matte white (205-225 with 210 advised) Other feedback, tips or thoughts welcome as well of course!
