Notice that it's a 1000mW engraver, i.e. a 1W engraver. For laser cutting, you'd want at least a 40W laser. So, that low cost laser is just for engraving, i.e. putting marks on wood, and shouldn't be considered for cutting, even balsa.

Yeah it sure would take alot of passes to get through what you want.

I've done up the cad for a estes titan nose cone,Does anyone with a 3d printer want to try it out ? I can't I do not have any more filament.

I got some filament yesterday from Amazon. I can't believe I got a package on Easter Sunday; the USPS label indicates Sunday delivery! I will PM you my details, I would like to try to print the Estes Titan nose cone you rendered.

For cutting fins and centering rings I was also looking at getting a DIY CNC Router Kit like: https://www.amazon.com/Control-Engr...YKAWS86XK2F3PWK

I didn't go this route because I want to cut all three or four fins (or centering rings) out of a stack of wood, all at the same time, so they are all exactly the same size. It is not clear to me if the CNC router like these can handle a 1" thick stack of birch ply. I may purchase a CNC router in the future after some more research. It seems to me that router bits are currently much cheaper than laser tubes, which is why I didn't even consider a laser cutter. Also it seems both of these cutters require a dedicated computer unlike a 3D printer.

You live in a special place to get Sunday delivery when in very recent history there was discussion of cutting the USPS down to 5 days a week on a national scale.

But when I chase this thing down to try to pick up more details, I found some answered questions over on Amazon
https://www.amazon.com/Engraver-Res...r+Printer&psc=1
where one of the users says the usable cutting bed is only 2 by 2 1/2 inches.
That's just not gonna do it for me.
But thanks for trying to help.

My understanding is that USPS only delivers Amazon Prime orders on Sunday exclusively due to a special contract with them and FedEx.
"Regular" mail and USPS packages are not delivered on Sundays.

I think that is still only in certain areas. I live in a small enough town to know all of our postal employees and none of them carry parcels on Sunday....yet.

To anyone that has a 3d printer and wants to try it out, I enjoyed doing the cad so much that I went ahead and did all of the pieces for the Titan 3e. My bird was missing the decorative tail cone, so the two parts that makes that up were guesstimated rather than measured. You can download the stl files from here.

I also did the Les offer the Estes Mercury capsule, as a commonly broken replacement piece. That can be found here.

Scott,

The Titan nosecone looks great, see pictures attached. I had some minor problems with my 3D printer, apparently I need to optimize some more settings. Did you intend there to be facets in the nosecone cap?

I have an original Titan II nosecone.
It does not have facets.
If the intent is to match the Estes cone, it is not correct.
