Thanks! I missed it. It looks like the dimensionless template in the downloadable Haute Route manual on the ATK site.
I did notice a small, 30mm line for verifying print scale, however. I may have missed that in the ATK manual.
When I draw my templates, the scale verification is a 4" x 4" box. It magnifies scaling errors (I verify with a dial caliper after printing) and allows me to check both x and y axis scaling - in case something wonky is going on with my printer.
I would have thought its primary benefit was to support the boot for folks who stomp big air. No?
