I started building the Cerberus 3D Printer but decided that my Prusa printed really well and what I really needed was a CNC router. I am re-using the 8015 extrusion and steppers etc. but these parts are not used in my new project. Most were originally purchased from Steve at Grabercars.com and are as good as new....
3 - 18mm O.D. Filament Reels
3 - 8mm I.D. V-groove idler wheels
9 - V-groove Roller wheels (802 bearings)
6 - 250mm carbon fiber push rods
So if you are building a Kossel or Cerberus etc., here is you chance to get over $100 worth of parts at a big savings.
Here is the link to my ebay listing....
