Prusa i3 3D printer modification

Dear friends! This is my model + build of my iteration of the popular Prusa i3 Single frame 3D printer. I also claim that this is the most accurate 3D model of it on the Internet. :) Feel free to comment, criticize, advise, etc. Also, the hot-end is my design, but in the build I bought it on Internet. I don't test my hot-end design yet. :) I hope that I will be able to make it soon. Best regards! P.S. I made some changes and added a PSU on the right side of the frame. The 3D model of the PSU is from here -> https://grabcad.com/library/switching-power-supply-nes-350 so all of the credits for the PSU goes to it's autor. EDIT: I forgot to mantion that the Electronics model is not mine as well! I downloaded from here, but I can't remember it's autor! So all of the credits for the RAMPS and Arduino boards are going to their autors in GrabCAD! ================== UPDATE 9/2015 Added my smart controller box's (from thingiverse) stls. Added my compact bowden extruder (self build, self printed) for 3mm filament. My J-head hotend is compatible with the fitting, needed for a PTFE tube, so I'll be able to make it to work on my printer, as well. Added my improved Z-axis threaded rods coupler for M5 nuts. This weekend I'll make the cable management (finally!!!). I ordered (from ebay) an aluminium building plate and an inductive sensor for autobed leveling, so...keep an eye on that project that I'm constantly improving! :)
