A modular tea jar lid, fits any jar with a 16 cm opening.
Slice with supports for the arc sections only, the pins and handle don't need any.
Print the following parts:
Arc Section x6
Pin x12 (Optional)
6 M3x15mm screws
Assembly is fairly simple, just print the parts, then use the M3 screws to bolt the arc sections to the handle. If you decide to install the pins, assembly the arc sections into sets of three with superglue or 5-minute epoxy, then glue halves together before installing handle with screws.
