[PSUBS-MAILIST] Printed Kort Nozzle

[Joe Perkel]

Jim,
 
Take a close look at the link provided by Alan. At first glance, that looks to me like the very components that make up the commercial fully assembled (minus the enclosure) offerings out there. I see a 3d print capability in my future then! 
 
I see now also home shop CNC (for a decent machine) is around 6K for bare bones. This has to come down some more.
 
I think my wife's prediction of her mad scientist husband sealed up in his laboratory just may come true! :)
 
Joe

Joe,
 
I had thought mortise and tenon to join the Kort sections together.  By M&T I mean of whatever shape you want, but most likely round such as in the Revell kits we used to build.
 
Also, it seems good to run guards from the Kort to the other end of the motor housing to prevent it getting caught on anything or sucking things into the prop.
 
Keep plugging,
Jim

Alan,

Are you here somewhere looking over my shoulder? :)

Here I am in the parking lot waiting to pick up my wife, perusing images of "interlocking joints" for ABS plastic, when your email came came through!

I like the Makerbot I think it's pretty neat!

Joe, 
I was re thinking your idea of a printed Kort nozzle.
There are printer kits for $900- that would do the job.
http://www.3dstuffmaker.com/

The ABS printer cable I've seen selling for about $1- an ounce.
The $899- version in the above link could possibly be big enough to print
the nozzle in one shot. If not then print it in sections & glue together.
My idea is to print the nozzle hollow with an egg shell wall thickness & fill it with
a fiber reinforced epoxy resin. The resin may need a few pours to allow for contractions
in the resin while setting.
Maybe under $30- in materials.
I am not at the point where I need this & neither are you, but I think this idea still
holds a lot of promise.
Regards Alan
