Lawsy's MK5 solidoodle extruder for ninjaflex E3D V6 edition

thingiverse

Update #2: The hole is too small and does need to be enlarged. I drilled it out with a 3/32" bit. THIS YIELDED THE FIRST SUCCESSFUL PRINT IN NINJAFLEX (at 230C) =D =D =D! I'm working on a new design to fix these problems, but there are mesh errors in the original file that are difficult to work with. Stay tuned.... Update #1: Cura produces errors but Slic3r prints great. The ball bearing needs to be the same diameter as the hobbed bolt in this design. Mine is too big and I had to melt material away slowly using a heated screwdriver. An attempt to merge the ninjaflex feature with the E3D V6 extruder. There are currently two issues -- the curvature of the roller bearing doesn't quite match and had to be dremmeled slightly The hole is a little rectangular and filament friction is high. Small 1cm cubes of ninjaflex fail 20% in. There is also a strange ridge which should not be in the model but appears in slicing and keeps the E3D from sliding into an already tight fit. I had to shave it down with an X-acto. The fit required large clamps, which is not ideal. Consider this model, for the time being, extremely experimental. Instructions You will need support material because of the bottom gap and cura seems to remove some of the built-in supports.
