Material swatch which will work for FFF/FDM & SLA printers, includes a thickness gauge section as well as an ISO style test coupon.
With the test coupon removed the swatch is the size of a standard business card (except 3mm thick), the 5mm hole in top left corner allows the user to attach multiple swatches to a key ring, chain or other fastening device. A business card holder like the one in the link below can also be used to store several samples.
The ISO style test coupon can be used for bench marking material strength with consistent results.
EDIT: V2 updates the text sizes, spacing and layout to improve print quality. Suggest printing with 0.25mm layer height to ensure depth gauge is accurate, alternatively you can print in thinner layers to equal final sizes. I suggest printing with a heavy infill to get a more realistic test coupon, or keeping all prints for benchmarking a consistent set of parameters to not skew the test.
