My latest “need that, so why not make it on the Glowforge” project. I wanted to make some holders for a couple of handles that had radiused edges, and didn’t have a gauge to measure them. I looked on line and in the forum but everything I found that I liked was metric, and I wanted imperial measurements. Low and behold, my version of an inside/outside Radius Gauge:
I used Rowmark Two-Tone Brushed Silver/Black Acrylic, and just used the settings for Medium red acrylic, with a Draft engrave. I should have dialed in the settings for the engrave, as the text came out a little rough. It’ll serve the purpose though.
