RSPB Bird Feeder Replacement Base Section

RSPB Bird Feeder Base by AmuseboucheUK

Design: FreeCAD Parametric

I have designed this replacement base as the RSPB bird feeder base tabs break off.

My final design has a base dia of 70, 20 high, the insert into the cage is 59.25 dia x 12 high with a 20 degree cone taper.
The three tabs are 19 wide with two lugs 2 x 2 x 3.5 with 11 gap between the lugs.

Material: PLA+ used (may need to use PETG if it is a hot summer, it's winter here at the moment so we will wait and see!)

Infill: 10%

Supports: Tree Touching Buildplate.

Any feedback welcome
