Turok's Razorwind 1:1 prop (dual extrusion)

thingiverse

I'm a complete novice at 3D design, and this was my first attempt at creating something larger. As a result, the mechanism is quite slack, and I'm sorry to say that it doesn't have a fillet in sight like its original N64 render. The model uses a free-wheel ratchet and pawl mechanism to facilitate spinning. The ratchet drive/hub measures about 230mm x 230mm, which is a bit unusual, but I wanted it as big as my bed would allow. If your bed isn't large enough, simply reduce the size of all parts uniformly or split the ratchet accordingly. There's plenty of tolerance, so a reduction in size shouldn't affect operation. As shown, I also printed a 40% model, which still works well. To print this project, you'll need to create: 11 plain boss and blade combinations without supports (I recommend adding a brim for stability) 1 pawl boss and blade combination with supports everywhere 1 ratchet hub and insert combination with supports (just touch the build plate) Print parts in the orientation provided to ensure a good finish on the 11 blades and excellent strength of the pawl and ratchet. When removing support material from the pawl boss, be careful – I found that a zig-zag support structure worked well. Assemble all parts with a suitable adhesive applied to the tabs of each boss and the underside of blades. A flat surface helps ensure true alignment of the bosses. I suggest making up 6 and 6 halves and then bringing them together around the center hub ratchet. There's about 1-2mm tolerance on all parts, which is slack enough that it should assemble easily and spin freely. Please see the attached demo video for a closer look. Thanks for watching!
