Safari hat has memories of grandfathers beekeeping hat, over which was a veil net. (It should have used an "ellipsoid" rather than a sphere.)

Two are fillet voronoi's, on which new Batch Fillet was applied to round corners, before surface ellipse. One of which utilized Blend Cap, giving slightly "wrinkled" surface.

One is skinny ellipsoid.

Still learning how to use imgbox site...There seem to be multiple permutations.
Only one of the above 3 links need be used. There are arrow keys for the other images...

I've been making an enclosure for Prusa 3+ filament printer, for printing higher temp filaments like Nylon, ASA, and Polycarbonate.
It is cubical, and uses 2020 aluminum extrusions, 6mm polycarbonate sheets, ventilation with activated carbon for the noxious fumes, etc.
