Frame for Cymbal-clock

I made a clock of an unused cymbal, which looked nice but it wasn't easy to see the correct time, since there where no hour-scale on the clock. So i made a removable frame, which fits on the clock and provides the scale. The frame fits on a cymbal with 250mm outer diameter. it uses a brim on the inside, since the frame is only 2mm wide.Make sure to clean the print plate or it won't stick.Make sure to remove the flow calibration line before printing the first layer
