This is my first thing that I have made with openSCAD. It is coffee tamper for my Tchibo Cafissimo where I do not use the pods but grinded coffee. Everything is parametric so you can just change it to satisfy your needs. edit: the first TchiboTamper had a bug in code, so the final print will be two times larger. In TchoboTamper-v2 is this bug repaired.$fn = 100; tamper_radius = 37.5; tamper_height = 10; holder_radius = 10; holder_height = 50;
