Hi... glad you like it - I already mentioned the details in the comments for an earlier photo of the same Flickr album:

It originates from Johann's Mini Kossel:

In fact this extruder works fast & reliably and without any need for maintainance for several months now. The drawbacks are:
- planetary gearbox not cheap (ordered mine from the UK: [www.active-robots.com])
- even more so for the spur gear which drives the filament (luckily found the last one a local gear specialist had in stock, see the linked Wiki entry for possible sources)
- filament change takes longer and is less convenient than with the usual extruders (you can't just lift off the idler manually but have to command the extruder motor by PC or printer UI)
