About 2 month ago I bought a Tarantula I3 3D printer from Aliexpress. After getting it through customs and assembling it, I must say it is one of the most challenging and rewarding projects I have ever worked on. I only had time to work on it during weekends, but now I must say I am quite satisfied with the results. There is room for improvement, but that will come at a later date.
Status right now
3D printer operational, 1 role of magenta filament installed
printed a radial fan fang to improve future print accuracy(and then printed a new and improved one)
installed OctoPrint on a RaspberryPi 2 and connected it to the printer
