Hi I noticed that the up! Has a unused connector on the pcb of the extruderhead. I was wondering If I could connect a extra fan on this connector (it looks exactly the same as the connector that connects the standard extruder fan. looking at your pictures I saw you connected a extra fan to this free connector. Did you used a normal 12 volt pc fan or a different voltage?
Sorry for the delay - only just got around to fitting v1, which didn't work for me (alignment issues with the pen clip I suspect). I like the fan mounts - my experience has been that keeping the stepper cool is the biggest factor in getting reliable prints
I'll try to find time in the next week or so to try v2

Version 2 has been released with fittings for two 50mm fans (to suit heatsinks) and adjusted filament outlet and air line positions to minimise mis-feeds.
New files below, and am keeping the originals for those who don't want to add a fan.
Buy an Artline felt pen (this is an Australian brand pen with a steel pocket clip - see here pelikanartline.com.au/index.php?option=com_content_ex&view=category&layout=multi-view&id=69&Itemid=154 )and remove the steel clip from the lid.
Print out, clear all holes and guides and install pen clip as shown. Install onto servo motor, and ensure the clip clears the gear.
Reinstall onto printer, and extrude!
You may need to adjust the size of the outlet guide hole if your spool curls too much (only open it up a little).
This is a prototype design, but has been tested to work with some pretty bad filament!
