This is a printable version of http://www.thingiverse.com/thing:4017 which is a derivative of http://www.thingiverse.com/thing:1351I do not have a heated build platform and I am pretty sure this will warp if you try to print it without. Like before, you will need to modify your weird dino or something if you want to use this with a stepper motor. So with that being said, this is experimental, but in theory it should work.I have also included the Sketchup file.Thanks goes to dsralph for the idea to print this.EDIT: Updated STL files. Due to stupid STL export from Sketchup, the others were not goodly... This are much happier! :DPrint one of each STL. You will need to make a plunger thing to push against the plastic like the original.Put it together. (Self explanatory, but if you need help head over to www.thingiverse.com/thing:1351)Mount it to your Dinos.
