Prusa i3 IPI rework

thingiverse

This is my own version of the Prusa i3, based in lots of ideas found here that have been mashed up with my own. Improvements over the original Prusa i3: -Adjustable belt tensioner for both Y and X axis. -Firmly secured endstops, with adjustable screw for Z and Y axis. -No messing-arround cables design; Cable-chain guides are arranged all over the printer. -Universal and simple extruder mount. -Reinforced averall structure. -Clever structure for the X axis; designed to neutralize efforts on the tranversal direction of the Z guide bars that come from the tension of the X belt. -Note descriptive picture. Red arrows show forces due to belt tension and actions that result in compression efforts, applied on the X guide. This config avoids flecting efforts on Z guides (Blue) .rar files available with all the components needed. (Z axis.rar - Y structure.rar - Y carriage.rar - X structure.rar - Extruder.rar - Other.rar) -The extruder included is exatly the same as the Johnash's extruder. UPDATE: Ventilation support for small vent added. Improved extruder support (V1 was affected by heat, now it's been reinforced and cooled down). Improvements in X axis structure and Z adjustable endstop system. A .rar file, called "Prusa i3 IPI rework V2.rar" can be found with all the updated components. Extruder can be found on thingiverse, same as the frame (sources) Check the X-motor modified version for Pololu nuts and Acme lead screws remixed by "Thehebs": http://www.thingiverse.com/thing:976946 Check the X-motor modified version for M6 nuts remixed by "GarryBu ": http://www.thingiverse.com/thing:1044485 UPDATE 2 Added instructional videos. Check the instructions page for advise! Instructions Avoid PLA for the extruder support. This part is heavily afected by heat accumulation. ABS will be more resistant. It is also very recomended to add the fan and also try to insolate the support on the internal faces. Check the part list attached to see all the comercial components available on thing files. Check instructional video on the description for the mounting details. Keep an eye! I forgot one important detail on the Y axis assembly video. DO NOT FORGET to add the whashers and nut that secures de Y axis to the frame! Otherwhise you'll find that you are missing those and you'll have to dissasemble the wholy Y axis again. To understand what I mean, check the Final printer assembly video, where these nuts can be seen on the Y axis.
