Was asked to make a nice vase cover for the grave's vase. So measured, cca 6,3cm diameter and made one. Asked about a led candle, so added there a cover for it. One is with a hole as was asked if I could also make one like that.
For screws used this video for Freecad:
Note: The Vase has no water outflow, so frozen water could brake it in some way.
Printed with unchanged Prusa Mini 0,2mm Quality profile.
For the top, there is no need for any support as is hollow made.
For the bottom it is needed (head down) is need for support around the screw.
