Spool holder with bearings

thingiverse

**EDIT April 27, 2018 :** After using it for days, the arm bends due to spool weight. I uploaded a stiffer version of the arm called Arm (reinforced).stl. Maybe another option would be to print it in less bendable material. As the tornado comes without a spool holder, I needed to print one. I wanted a solid and bearing spool holder to screw on an aluminum profile or control box directly, so I made this one. Even if I've done this for the Tornado, it's compatible with all printers of course! I hope you will like it! What You Need: - 2 x 608zz bearings (skate bearings) - 3 x M8 nylon locking nuts - 1 x M8 rod of 13.5cm (5.315") - Plastic parts - Pliers Print Settings: - **Arm:** No supports, 0.2mm is good and 50% infill - **Spool holder:** No supports, 0.15mm and 25% infill - **Rod support:** No supports, 0.15mm and 50% infill - **Cap:** Supports, 0.15mm and 20% infill - **Rod support nut:** No supports, 0.15mm and 30% infill Notes: Look at the assembly video below before you start. You can secure the second nylon nut tightly, but don't tighten the third one too much or the spool holder won't turn freely. Leave a little play.
