Yeah the guy with the 3d printer said his printer isn’t big enough for this kind of project but he does experiment with different types of resins and plastics.
He essentially said that if i were to find someone with a printer big enough that it may be worth having a softer filament rather than a hard setting resin.
other than that i have a tab open on eBoosted for enclosures and am trawling the sales page looking for battery builders.
