Owl Solar Light Lense Repair

This is a model of a replacement lens for an owl solar light; one of the originals had broken and they had both yellowed tremendously due to UV.  I know these lights are a bit naff and I should just chuck it out, but it has some sentimental value and this is a good excuse to print something actually useful for a change.

I've printed this pair of replacements in Clear Petg with the pupil in black Petg using the colour change at height function in prusa slicer.
