Made a knife sharpener that uses skateboard bearings in the center to roll smoother. I left this at default settings for the P1P, have printed both PLA and PETG great. Any skateboard sized bearing would work and they just push in, no glue needed but will take a little force. Uses 10x2mm magnets for the stone and the angle. I also added a 12deg and 15deg double sided magnetic holder, but if there's an angle you need let me know.
