I wanted to use the Springtime in Kyoto and Waves of Good Fortune patterns from the GF store to display earrings, and needed a way to stand them more upright rather than tilted back, hence this mod. Then I shrunk it to make one to display my etched tiles.
The larger one is sized for 0.19" material (mine are cut from Home Depot chalkboard), and the smaller one for 0.13"ish stuff.
I noticed that when I cut these, there was a duplicate cut. I tracked it down to the svg file – both of the parts (small and large) with the notch at the top had a 75% duplicate path. Here is an updated file with this extra path deleted. The notch sizes are exactly as @geek2nurse designed.
