Made it for my wire spool which always gets messy. Designed for less wire bending when wire comes out, also good outer look. I tried to attach a blade, but really I could't get the proper place for it. sry :)

0.15mm layer height and 0.3mm line width for the best result. Please flip the lid before printing!!

EDIT : Moved completly to Freecad, fixed some design flaws.(v3, final version)
