I found this by searching the archives, which yes Charlie, I agree they can be difficult at times but I'm still really happy they are there and use them often/occasionally.

So to continue sharing this artwork I just put the graphic in different formats and put them all in a shared google Drive folder

The .svg file is a vector graphic which can be used in Inkscape or Illustrator

The .dxf file is for most commercial and some hobby cutting machines.

The .studio3 file is for use directly in a Silhouette Cameo3 cutting machine

-note that with all these files the text relies on your installed fonts on your own PC, so you can change to whatever font style you want but if you want the same one that I used you will need to have it installed. It is Terminator and I uploaded the correct .ttf file as well. Just double click on it and your computer will correctly install it for you.

and of course for those that just want the image there is a .png and a .jpg

Now a little off-topic but for those looking to purchase their own cutting machine I would say it is well worth it. It cost me far less than getting it done professionally and it was fun, sort of easy and I'm quite pleased with the results.

  There are 3 main brands to choose from. Cricut, Silhouette, Brother. All three of them are reasonably priced but have limited design software geared toward arts & crafts types, but all have "membership" options that for a price (yearly subscription) will supposedly open up an entire world of wondrous possibilities for you. Don't do it. 

The Cricut is rated as slightly better than the others, but it can only cut a maximum of 12"x24" and it's software is web based with no way to import .svg or .dxf files. Good for scrapbooking with the ladies club I suppose.

The Brother also seemed like it was going to need extra purchases and it was lowest rated (but still good) so I didn't look much at that one.

The Silhouette Cameo3 is rated in the middle, but for doing airplane or other vehicle graphics would be best for us as it can cut to a maximum 12"x120" (be sure to buy the optional $50 roll feeder if doing long stuff). It can also import .dxf files directly with the basic free software. You need the pro software to import .svg files. This allows you to do your own design work in InkScape (free & powerful) or Adobe Illustrator (not free, but powerful) and then export your vector graphic as a .dxf file for immediate use in your Silhouette cutter software.

  It's really pretty easy and allows you to put a personal touch on your own plane. And I think most builders that are willing to pursue an alternative engine for their project can and probably should do the finishing touches as well.

It can also do a multitude of other things including doing your own t-shirt using the heat-press vinyl instead of ordering from the above link
