Regelbau R502 - Command Bunker - STL


The Battle of Merville Gun Battery occurred on 6 June 1944, as part of Operation Tonga, part of the Normandy landings, during the Second World War. Allied intelligence believed the Merville Gun Battery was composed of heavy-calibre guns that could threaten the British landings at Sword Beach, only 8 miles (13 km) away.


The type 502 bunker is a very similar design to the type 501in fact, it can be fairly accurately described as two type 501s grafted together side-by-side. Its name reflects this: the 501 is an einfacher Gruppenunterstand (single section housing), while the 502 is described as a Doppelgruppenunterstand (double section housing). Just as the type 501 was superseded by the 621, the 502 was replaced by the later 622 in the Atlantikwall. At least 1,718 type 502s were built, however.


This STL file is designed for FDM Printers and print with a 0.6mm nozzle at 0.3mm layer height. 


Supports are not needed for this model. At larger scales these bunkers may become larger than more common build-plate sizes, you may need to cut them into sections for your machine. Please check the size below. 

The 1/100 scale model has been cut and jointed to allow printing on common size buildplates (220mm x 220mm)


The printed model measures approx.:

534mm x 210mm x 95mm @28mm Scale

351mm x 138mm x 62mm @00 Railway scale

267mm x 105mm x 48mm @15mm scale


We have a handy calculator for resizing files for 3D printing over at scale-converters


It is designed for 28mm table top games set in WW2 such as:

Bolt Action, Chain of Command and Konflikt ’47. It can also be used in games such as Judge Dredd, Necromunda and Fallout Wasteland.

Now rescaled to for Flames of War, epic and 00 railways by popular demand.
