Lawsy's MK5 solidoodle extruder for ninjaflex E3D V6 edition

thingiverse

Update #2: The hole is too small and urgently requires enlargement. Drilling it out with a 3/32" bit yielded the first successful print in Ninjaflex (at 230C), delivering much-needed joy! I'm now working on a fresh design to rectify these issues, but encountering troublesome mesh errors within the original file that make them a challenge to tackle. Stay tuned... Update #1: Cura generates frustrating errors while Slic3r produces fantastic prints. The ball bearing must match the hobbed bolt's diameter in this design for perfect fitment; unfortunately, my bolt is too large, necessitating melting away excess material using a heated screwdriver. A failed attempt to merge Ninjaflex features with the E3D V6 extruder currently exists due to a mismatch in roller bearing curvature, which needed minor Dremel adjustments The hole's slight rectangular shape leads to excessive filament friction. Even small 1cm cubes of Ninjaflex suffer 20% failure rates. Furthermore, an unwanted ridge inexplicably persists within the model but manifests during slicing, forcing me to shave it down using an X-acto to achieve smooth E3D insertion into a previously tight space. The necessary use of large clamps poses some problems. Consider this design purely experimental until further notice.
