Looking for single or dual extruder or triple extruder designs to use with my bowden tubes for my Rostock Max. Any suggestions? I currently have 1 EZstruder on the odd looking smiley face holder. I don’t have hobbed bolts yet, but I think I could make some.
Do you mean a design with 3 tubes and 1 motor?
No. I doubt such a thing is even doable.
I am going to install another hot end soon and I just need a good bow den extruder to feed it. Of course, if I can make things look nice and be upgradeable, that would be preferred.

I know it’s not what your’e looking for but maybe some others are interested in a single motor for multiple filaments. There has been a few designs that use a single motor for 2 or more filaments.
Stratasys (and a Kickstarter) have a design where 1 motor drives two filaments. This design takes advantage of a rack on which the motor slides. When the motor changes direction a gear system makes it slide sideways causing it to squeeze the new filament between the hob and idler.
There are some other designs that involve a cam driven by one motor and a motor to drive all of the hobs. The number of filaments that can be driven is dependent on the precision of the cam system. The cam is used to select which hobs/idlers are engaging the filament.
I think this is more like what I need.
I use these and will be stacking 4 of them with the Kraken http://www.thingiverse.com/thing:60531
@Tim_Rastall Do you have a picture of those on a delta printer by any chance? I am not exactly sure where I would be putting it.
This is the best I could find : http://2.bp.blogspot.com/-7c2NMNWucCk/UTsm-dL81-I/AAAAAAAACm8/2TIYSK0E4C8/s640/Tantillus_in_Rostock_closeup.jpg
I like this minimalist extruder
It mounts directly to the motor, or you can pinch an angle bracket between the mirror and the extruder. Really small. I think this is really similar to the one that was confused as gun parts in the UK, SMH
What I need must have a bowden output.
I’ve got a beefy Wade-derived version: https://github.com/paenian/bertha/blob/master/extruder/jonaskuehling_gregs-wade-v3%20(repaired).stl
Bolts onto extrusion sideways, the bottom hole is meant to be tapped for a pushfit connector. I’m using two of them on my delta now, one 3mm and one 1.75mm.

@NathanielStenzel , yeah, you can mount the pneumatic fitting onto the bracket. I forgot to mention that it required a bit of extra design.
