For Day 5 of 30 days of creativity ( #30DoC ) I give you another addition to the Quick-fit family, here is a Quick-fit X carriage and mount for the Printrbot. Designed for any extruder's that can go on my Quick-Fit X carriage. http://www.thingiverse.com/thing:19590** - Sketchup files now uploaded :)Make your Printrbot easier to switch extruder's and give yourself a new X mount.Print out the two plates and replace the X carriage on the Printrbot.It also needs the Quick-Fit catch from Here - http://www.thingiverse.com/thing:19590 Print a Quick-Fit Extruder, see link. It's designed to be used with Extruder's that use the Quick-Fit X carriage. http://www.thingiverse.com/thing:19590I also re-made the X Axis mount with 3 Linear bearings instead of just 2.It all fits and operates on the Printrbot, but limited testing so I'm going to say it's a work in progress until I have done some more printing with it.Made for Day 5 of 30 days of creativity ( #30DoC ) http://30daysofcreativity.com/See my blog for updates and other printing advice - http://richrap.blogspot.co.uk/2012/06/quick-fit-extruder-mount-and-x-axis-for.html
