Here's a handy little file that can be fairly versatile...
you can vary the height.
I like anything from 2"- 8". It may not be as stable if you go too tall.
Instructions are on my blog here. The file is at the bottom of this post...
I use two sheets of paper...I check the "keep proportions" then select 11.5"
which will give you the first page
then in the "x" box I put in "-11.000" to move the file
over to cut the second page.
If your browser is giving you a blank box or something else, right click on the link and
select "Save link as" or "Save target as" the save dialog box appears and you can save the svg.
If you still can't download you may have to use a different browser like Firefox. Internet Explorer can be picky.
If you are having problems you may email me directly for the file at email@example.com
Here's a zip file with the svg and picture file for those having trouble downloading the above svg or if you prefer.
