This is a FIRST Tech Challenge (FTC) Robot Sign Inspection Tool for the Decode season. Inspired by jgroppe's contribution last year (https://www.printables.com/model/1060891-ftc-robot-sign-sizing-tool) I've created an version suitable for this year. I've printed it in a high contrast as shown in the photos for easy reading and finding 😎.

With the ranges allowed this year, the left side of the sizer deals with the sign minimums (both text height and sign height), while the right opening show's the text maximum (no max sign size). The 0.25" edges make it easy to check the exposed border requirement.

Feedback welcome if anyone finds an issue. The model is available as a STEP file and as an STL. Added metric version as well due to requests. 

I'll also upload this to Makerworld as a colored 3mf. I printed the example with 0.4mm nozzle, 0.2mm layer height, 3 walls, and 1.0 mm top and bottom full thickness. Stronger than default but helps to make this stiffer and less likely to get bent or broken with rough handling. If printing in a single color, just use a sharpie to color the embossed text.
