This is a little test cube design using Openscad that you can use to quickly test the optimal slicer settings for your printer.
The cube has thin walls with holes and a bridged top, so you will need good bridging settings and retractions to get a nice clean print. The cutouts in the sides will also show up any ringing usually caused by loose drive belts.
As the walls are thin it prints quickly too!
My test print photos show some ringing on the edge of the triangular hole, but the top bridging was very good.
If you are new to Openscad, this is a nice simple piece of code with a structured architecture and some debugging tips. I use this skeleton framework for all of my Openscad designs.
The was printed on a K8200 with the upgraded extruder and 0.35mm nozzle.
