Regelbau 501 (Merville Battery) - Personnel Bunker

Regelbau R501 - Personnel 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 German type Regelbau 501 bunker was designed in 1939, as part of the planned Westwall defences against Francethe German counterpart to the French Maginot line. After construction of the Atlantikwall was started in 1942, the Regelbau 501 was built there as well, although it was later superseded by the Regelbau 621, which was roughly the same size but of more up-to-date design. At least 1,519 Regelbau 501 bunkers were built during World War II.

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 printed model measures approx.:

330mm x 198mm x 82mm @28mm Scale

217mm x 130mm x 54mm @00 Railway scale

165mm x 99mm x 41mm @15mm scale

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.
