anet a8 display buttons cover

Just an exercise to verify if my own anet is capable to print small circles and thin walls.
these are the cover for the display buttons.
please note that i own a 2018 anet a8 and i measured its display and frame so buttons may not fit in older versions.
for your reference:
button are 12mm diameter
body is 8mm diameter
inner hole is 6,80mm
