About this model

I wanted to have a test print which I can use to test the dimensional accuracy of my printer and the print quality of my filaments. But it should also be pretty enough to keep as a color sample afterwards. So I created this 30x30x30 mm cube which contains several functions. The print takes a bit less than 1.5h. Below are pictures from which you can take some measurements to check your cubes for dimensional accuracy. You can check the following properties on this cube:- stringing- bridging (are the bridges over the letter clean, including the large area inside?)- ghosting / ringing- overhangs- dimensional accuracy in all axes- first layer height (is the logo clearly visible on the underside, are there holes in the narrow areas?)- Was the helix printed neatly with a single wall line?- Are th…
