Should be self-evident, let me know if you need repro

Actual results

$ ~/Downloads/CrealityPrint-V7.0.0.4127-x86_64-Release.AppImage

Having to add:

{ lib, config, pkgs, ... }:

#! System Appimage Management

let
	inherit (lib) mkIf;
in mkIf config.programs.appimage.enable {
	programs.appimage = {
		binfmt = true;
		package = pkgs.appimage-run.override {
			extraPkgs = pkgs: [
				# Some packages need this dependency, added for utility - https://github.com/NixOS/nixpkgs/issues/350383#issuecomment-2433316461
				pkgs.libepoxy

+				# Required by CrealityPrint 7.0.0.4127
+				pkgs.libdeflate
+				pkgs.bzip2
			];
		};
	};
}

Which is still not sufficient as the CrealityPrint is not accepting the libbz2.so.1.0 provided by bzip2 package:

bzip2.out 0 s /nix/store/xgavznqg1ay2hycpp7yy9ia1n751jcla-bzip2-1.0.8/lib/libbz2.so.1.0

Expected results

Open The Slicer and work without assumption that the distribution will include common dependencies as impermanent systems prefer minimalism.

OrcaSlicer doesn't seem to have this issue beyond missing libwebkit2gtk-4.1.so.0
