A re-designed UP! Extruder Feeder/Cable Tray design. Removing the roller bearing and housing and replacing with spring steel guide element. This gives greater flexibility in filament thickness diameter, along with the added simplicity of design. Includes a fitting for air line supply to cool the extruder gear.


UPDATE 03/08/2012

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 http://www.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!

I think this is exactly what I need! My Afinia (an Up! release to the USA) has been clogging because it can't push the filament through because the plastic of the extruder is stretched and can't provide enough tension against the gear. This is a life saver! At least, I hope it is, and I'll get this printed up as soon as possible to get this thing back on the road. I got printing to do :D

Also, is this a direct replacement? It looks like it is, and that'll be excellent if it is. All but the pen spring, I can manage that part. Great work!!

How do you attach the fan to this part?

Nice, will this fit the Mini as well?

Doesn't work... the piece lacks proper filament guide at the bottom and filaments gets bent....

That has always been an issue - I haven't had requirement to fix it yet. You need to guide it through prior to using it.
Other than that, it works perfectly, I have been using this extruder for the last 2 years without an issue.

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?

A year late, but just saw this post. Yes, its a 12VDC fan - you can piggy back off this without an issue.

Thanks for your reply! I have already tried pluggin the fan in the spare connector, put unfortunately it does not work. In this pp3dp tread (http://www.pp3dp.com/forum/viewtopic.php?f=18&t=51131)http://www.pp3dp.com/forum/vie..., someone stated that this spare connector is used to power the led's in the up Mini en therefor has no function on a up plus?

Not sure buddy - I have an original UP so this may be slightly different to an UP Plus. Do you have access to a multimeter to check the pinouts?

The clip from a Pilot "Precise V7 Premium Rolling Ball" pen also works. These are readily available in the U.S. from most office supply chains.

Nice looking print! Madox put me onto your post, and I can't wait to try it on my up as well.

Come check us out at Robots and Dinosaurs sometime. I think you'd fit in nicely!

Nice! Will try it out this weekend

From your thread I see you are in Sydney, you might like to check out http://robodino.orgrobodino.org - there's numerous Up! owners that I suspect wil be interested in your design

Thanks mate! I just started getting the whole 3D printing game, so im learning alot really quickly!

Let me know how you go with it, and if you have any issues/suggestions! 8-)

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
