Summary

after printing this amazing item i had problems reading the letters.
so i decided to remake it with outward letters instead of inward.
i did my print on ender 3 v3 ke without multi color. but for this i used black petg and white petg.
startet the print with black petg.
added a pause to laýer 18 in the Creality Slicer. changed filament to white and resumed printing.
again at layer 25 i made i pause to return to black

after a little tuning with a black permanent marker at the inner edges its finish.
