At long last, after a few frustrating moments (the extruder head crashing into the build platform several times – ouch!) we finally have a successful print.
What was the first thing I printed? I tried a small, solid cube, but it revolted and slammed into the platform a few times… melting a couple holes in the plastic platform. So I moved on to one of the most popular models in Thingiverse, the website that stores all the 3D model files you can download and print. So…. I printed a bottle opener. It was big enough to print without the need for really tight tolerances.
