Diameter Corner mm Gauge Card

Corner Diameter Gauge Card (Metric)This is a simple, card-style corner Diameter gauge designed to quickly measure the diameter of filleted corners by direct comparison. Just place the card against the corner and match the curve—no guessing, no math.I designed this because most radius gauges available are stick-style tools that are easy to misplace. I wanted something flat, compact, and always nearby, like a business card.FeaturesCard-shaped design – lightweight, compact, and easy to storeMetric units (mm) – clearly labeled on the modelMeasures corner diameter / fillets by direct comparisonGreat test print – perfect for checking:Font clarityMulti-color alignmentSmall detail accuracyEasy to print – no supports requiredMulti-color friendly – designed so the text can be printed in a second colorDefault colors shown are red on green, but you can easily change colors in your slicerWhy I Made ItI needed a simple way to measure the corner diameter of my keyboard while designing a custom case.
