I have created a Multipurpose Jig in Autodesk Inventor and 3D Printed the Part in Ultimaker 3 Extended.I have uploaded the 3D File as well as the link to the making video posted above.
Here is the link to the 3D Model:
I'm trying to design an open source robot actuator for gripping CD discs.
The main applications I have in mind are either a disc duplicator robot and a jukebox/cd changer.
1) Needs to grip the disc edges, not center hole, so it can be used with cd spindle.
2) As slim a profile as possible to maximize the number of discs a jukebox rack could hold.
Below is a rough model of what I'm thinking. As you can see, I'm still undecided about the best method for servo attachment.
Any feedback or design suggestions?
so how a lot of custom jewelry is made, especially rings, is they start from a wax model, which is cast in plaster, melted out and replaced with a precious metal.
has anyone done the same with a hollow 3d print to cast something out of a non ferrous metal?
I'm trying to design a general purpose sensor/scanner device. The idea being to use a single sensor of some kind, which is then swept through every point in a 2d plane. (circular or rectangular, doesn't matter) The question I have is what kind of mechanism to best do the sweep?
So far I've considered:
Cartestian X-Y (reprap-like) = I don't like because it uses two motors and sophisticated control.
Sensor rides on a planetary gear = better, simpler, but will create a greater density of readings near the center. Also I'm not sure about "retrograde" movement re-sampling old points when I could be moving on.
Any other ideas?
