I guess it's risky to reuse another hoaxer's model — if the earlier hoax gets debunked, it could expose the new one as well. It's safer to come up with a completely new design, inspired by the UFO mythology of the time.
Agreed. And a hoaxer thinking of copying someone else's picture or description of a UFO might be concerned that the person(s) responsible for the original would know the copied design was a hoax if the original was a hoax itself.
Maybe that's part of the current popularity of "orbs", any point lightsource in the sky
might be an orb, so lots of confirmatory "evidence" for believers if they don't think too much about alternative explanations.
A lack of features/ details prevents debunkers finding possible matches, like the gas lamp lids resembling Adamski's UFOs.
There's no risk of angry ex-partners pointing out the model-making stockpile in the garage.
Debunking one claimed orb sighting/ picture/ video doesn't necessarily debunk others, whereas few people are likely to take a new picture of an Adamski-style "scout ship" seriously.
And reports of orbs and their claimed behaviours (e.g. from Luis Elizondo) subtly invert Clarke's third law, "Any sufficiently advanced technology is indistinguishable from magic"; a glowing sphere, devoid of obvious structure, subsystems or means of propulsion, and capable of extraordinary manoeuvres (including passing through walls) is essentially magical- and therefore "evidence" of a highly-advanced technology...
Despite the
enormous proliferation of cameras (on cellphones) routinely carried by people since the mid-1990s, and of course the commensurate ability of people to contact others if they see something unusual, we rarely see pictures of structured UFOs as were sometimes photographed in the 1950s, 60s and 70s.
The Calvine photo, supposedly taken in August 1990 might be one of the last (arguably!) "credible" photos of a nuts-and-bolts UFO to get much attention- this in our era of clickbait and the widespread dissemination of silly, and false, claims. The one emblematic photo of a "black triangle" from the Belgian UFO flap of 1989-1990 was released a little earlier, June 1990:

The photograph was examined by a number of sources, including NASA, the French National Centre for Scientific Research and the Belgian Royal Military Academy, but none could positively identify it or find obvious signs of fakery.

In 2011, Patrick Maréchal demonstrated how he had created the hoax UFO, by cutting a piece of styrofoam into a triangle, painting it black, embedding a flashlight in each corner, and hanging it from a string.
As a quick aside, the secret US military aircraft in the second X-files episode (September 1993,
https://en.wikipedia.org/wiki/Deep_Throat_(The_X-Files_episode), strongly implied to be based on reverse-engineered ET technology, might have been partially inspired by the Maréchal hoax picture- a triangle with a bright light at each point and a circular spotlight-type feature in the centre.
I miss the old nuts-and-bolts UFOs, they were much more fun. Shame that the ET technology has improved so rapidly
