UPDATED : 19 November 2012 : Johann has merged the corrections into his master branch, so you can use those now!Johann's latest masterpiece, the Kossel Delta, had some teethining pains when I tried to assemble it. Here are some modifications to the parts that were creating the problems!The latest Github versions of "corner", "frame-endstop" and "frame-motor" where thickened to 3.6mm. This increase in thickness caused an offset on the vertical beam moounting screws. If you've already printed the Github originals, it's entirely possible to sand the inside edges and re-drill the holes.These pieces adjust for the increases depth by adding .5mm gap to compensate for the increased thickness. Please note that the license on these parts will be modified to reflect Johann's when the Kossel is published...
