Summary30mm diameter with aggressive grip around the edges. Print with a 0.1 layer height to get the best grip. Comes in: M3, M4 & M5 versions. I made this one because I was not getting the desired results with the numbers and ticks. They always came out hard to read or see.Print SettingsPrinter: ORD Bot HadronRafts: NoResolution: 0.1
