This Model is largely based off of Skyfox3Ddesign's "Schwerer Gustav 1_72 part 1". If you want to bring the original to trench crusade or use parts from Skyfox3Ddesign's "Schwerer Gustav 1_72 part 2" you should go check out those two designs and scale them up by 128.57%.

If you want to build a track for this weapon you will need to scale Udos3DWorld's "Basic Rail System for 28mm Wargaming" to 81.27%. I don't know what rail scale this would be close to.

I decided to use Schwerer Gustav due to the Lion's paws in the art appearing to be placed over two separate tracks. I also thought that with Trench crusades already wacky sense of scale wouldn't make this too out of the ordinary. The art appears to show a Church like structure being built around the ammo handling platform. I believe this was added after the gun was turned over to New Antioch or after the gun's abandonment.

If you want to remove the church all you have to do is replace a few of the parts with Skyfox3Ddesign's original files. Each item is named after the file it replaced so you can easily find its counterpart in the "Shell Handling" and "Main Chassis" folders. My files have been scaled to 28mm so you will need to scale up all Skyfox3Ddesign's by 128.57%.

I haven't printed this yet but it is currently optimized for a FDM printer.
