Two-Stage Tentacle Mechanisms Part III: Putting it All Together

Welcome back to the final chapter in our journey exploring two-stage tentacle mechanisms. This is where we arm you with the tools and techniques to get one of these cretins alive-and-kicking in your livingroom. In this last installment, I’ll guide us through the steps of building our very own tentacle and controller identical to one we’ve been discussing in the last few weeks. As promised, this post comes with a few bonuses:

Design Files

  1. The Almighty Bill-o’-Materials
  2. Vector Drawings for laser cutting
    1. DXF files pre-offset (0.003″)
    2. DXF files original
  3. STL Models for 3D Printing
  4. Original Tentacle CAD Model Files
  5. Original

How To Build Anything With Delrin And A Laser Cutter — Advanced Tricks

Everyone wants their prototypes to look polished, as opposed to looking like 3D-squirted weekend afterthoughts. The combination of Delrin and a Laser Cutter make this easy, especially if you learn a few tricks-of-the-trade that will make your assemply pop, both functionally and aesthetically.

Last time, we took a deep dive into fabbing parts with Delrin and a typical 40-watt laser cutter, and we discussed some of the constraints of the material. More recently, [Gerrit] gave us a close look at the material itself. It’s been about a year since our first post, but the list of tricks is far from …read more
