This thingi is 334 mm tall so I had to section it into shorter chunks in order for my printer to handle it. Even still I have published the entire stl also. The walls are .4 mm thick. UPDATE: During my printing I noticed problems that I had to overcome. The files are labeled with "-2".Print however you think is best. It took an hour and a half for me to print the bottom at 3.6 infill. Maybe someone could tell how it prints for them. I have a homemade prusa and am still using Repsapper, which really isn't to bad once you learn all the ins and outs (even though I haven't learned them all, lol).
