Of Course It Was Built By a Little Freak

That lightsaber pod was built by the designer of the Halcyon itself, Shug Drabor. In true transmedia crossover potential, and because apparently everything must be designed after after Rise of Skywalker, Shug is an Anzellan, the same diminutive race as Babu Frik.
Shug didn’t just design the Purgil-class, but established Chandrila Star Line itself, spinning out into luxury travel from his days as a charter company owner with his mother on Chandrila. The Halycon’s engines are shaped in a “Drabor Configuration” in honor of him, but really, it’s mostly just that he’s from a race of little guys from the most recent movie.
