Belt Drive Extruder

Hey I saw this new extruder design a little while ago but cant find it anymore and was wondering if anyone knew anything about it. Now i am not referring to what you find when you type belt drive extruder into google. I do not mean that it uses a belt to turn the hobbed bolt, I am referring to one without a hobbed bolt and used a belt to press against the pulley inside the extruder.

Anyone know what I am talking about or anything more about it? Good/Bad? Link to more info on it?

Funny, I stumbled across it this morning on 3D Hubs. Think this is what you are looking for? https://www.3dhubs.com/talk/thread/new-type-cold-end-vaeder-v-struder

Yeah, the Vaeder is most likely the one he is referring to. The other similar one is the librostruder, which doesn’t actually use a belt but uses the same general feed principle.

@deejayspinz YES that is exactly what I was talking about and couldn’t remember where I saw it.
