Z Axis mod for i3

thingiverse

This is a modification for the Prusa i3. I designed a new Z Axis to work with the Y and X from the official Prusa i3 git sources. I am currently using this on my custom printer, with my current setup I have a Z height of 260mm. *Update** I've uploaded a v2 with better support for the Z smooth rod, and added a hook to make attaching to the Y bed easier. I also made the Z top wider and added holes to attach a zmax end stop Instructions **BOM The same as for a normal i3 just none of the parts need for the Z. **Full Printer The X and Y axis is straight from git://github.com/josefprusa/Prusa3.git Print out the parts for the X and Y following the normal directions. **My mod's Print two of each of the stl files. ** Z-Axis.stl You will need at least 115mm in Z height to be able to print these, you can edit the config.scad files and shorten the var 'arm_length', but you will lose X build volume by doing so. Once printed they are pretty straight forward to install. I included a pic that should help with most questions. The picture is of the first prototypes I printed the arms were a little short dropped my x build to 150mm instead of the normal 200mm, redesigned to get the full 200mm **Z-Axis-Top.stl These will print just fine on any printer. Once printed just place them on the top of the Z smooth rods and connect with a threaded rod, 8mm or 5/8 inch should work fine. ** Once assembled my current build volume is 200x200x260
