Cocoon Supports for tall-thin screws of Quadruple Portal Desk Toy by Ada Cohen

The tall-thin screws of this toy are easy to make out of machined billet, 3D powder binding, and 3D resin.

It is VERY difficult using 3D FDM (filament) printers because they are tricky to support.

Laying the parts down would work, but the shape will be deformed.  If I needed to print a leadscrew or a long splined shaft, the supports would leave witnesses and probably be distorted,

I came up with COCOON SUPPORTS.   They work, and I would like to present them as an alternate way to support parts for some tough cases.  I need to get some people interested in the process so that they can experiment with it and develop and improve the system.

There are details at https://www.cocoonsupports.com

Download the original models for the Quad screw toy thingamabob from Ada Cohen at    https://www.printables.com/model/427933-quadruple-portal-desk-toy 

and then download the cocooned versions of the screws to test it for yourself.

I have not modified Ada's model at all.  The end result will be exactly as it was designed.

I am just using this creative design as a test part to try Cocoon Supports.

Try it, experiment with different models.  Let me know.
