Using the awesome Macharius tank designed by Mkhand_Industries I put together this custom closed turret (Armageddon) Omega variant. This tank is scaled for Epic 40k however if you would like to print it for use in normal Warhammer 40k simply up scale it by 498.75%. The tank is currently one piece which is how I typically prefer to print on my Ender 3.

Macharius Omega Lore:

The Macharius Omega is a variant of the Macharius Heavy Tank used by the Imperial Guard. The Macharius Omega differs from the standard Macharius tank and its other variants due to its unique main weapon. The Macharius Omega is a war-machine built with a single purpose, the battlefield deployment of the Omega Pattern Plasma Blastgun.

This weapon is a variant of the common Ryza Pattern Plasma Blastgun commonly deployed on the Stormblade super-heavy tank. The Omega Pattern is smaller and lighter than the Ryza Pattern, as it uses a compact generator and smaller force crucible allowing it to be mounted on smaller armoured hulls, such as the Macharius. The downside of this version of the Plasma Blastgun is that it is less stable and generates considerably more heat than the Ryza Pattern, but fortunately it is also much easier to manufacture.
