I have been building all of the parts used on the TAZ 6 to get some experience with the TAZ 6 printer, and to have spare parts on hand. I found the hard way that x\_carriage\_guide\_v2.stl has the part upside down but x\_carriage\_guide\_v2-x4.stl has 4 parts right side up. But the biggest problem I have run into is that the y\_idler\_mount\_v4.0.FCStd is not the same part as the one that is on my TAZ 6. The one that I printed has the cylindrical cutout in the base extending under the smaller of the shaft supports. This is a structure that can not be properly built without support material since there is a part of this bearing support that hangs down. The one that is on my machine does not have the cylindrical cut out extending under the shaft support. On this one, the base is solid, and the shaft support is not hanging in air. I verified that the one I built is the same as what it looks like in FreeCAD, so the design file is wrong. Could someone please direct me to the correct design file? Thanks. Edit: added a picture of bad part. I should not be able to run a string through it the way I have. ![BadPart.JPG](https://us1.discourse-cdn.com/flex020/uploads/lulzbot/original/2X/8/871f3c53b10576a3200da0f0b4fafc6e029d99a4.jpeg) ---

Not sure why that swiss chease made it into the [download.lulzbot.com](http://download.lulzbot.com) folder, it’s definitly not correct. The one in the development folder here [http://devel.lulzbot.com/TAZ/Olive/production\_parts/printed\_parts/y\_idler\_mount/](http://devel.lulzbot.com/TAZ/Olive/production_parts/printed_parts/y_idler_mount/) is intact however and should be good to use. It’s the same file name, but it is the correct, non holy part. ---

This is much better, Thanks. Now I need to get some more ABS plastic. ---

None of the parts design files were on the SD card for my machine. Were they supposed to be on the SD card? I downloaded all of the design files from your web site.
