About this 3D model
This is a small adapter plate that allows you to attach a bowden tube to a (Greg's Accessible) Wade's extruder. I hacked it together based off of Mark's very nice bowden adapter and mount. (I just didn't need the M8 rod mount part... I use it with my own mounting block found here:http://www.thingiverse.com/thing:73763 ) I have included STL files for using an M4 nut, or a commercial Push To Connect tube adapter. The SCAD file can make either.
