[bfy.tw]

I have already searched but i can't find enough information about it?
But have you already used it? Which one have you used?
Where did you buy it or can you make it self?

The wade extruder is a relic from the past.

It is a geared extruder designed for 3mm filament that can't really be driven with current direct drive extruders.

Its a DIY extruder.... you print the parts get the other bits form a local hardware store/ebay and build it...
Most tricky part is the hobbed bolt... (also on ebay)

It works fine.

I used to use [www.thingiverse.com] way back when....
[www.thingiverse.com] is also good
