Regelbau R630 Large MG embrasure

Regelbau R630 - 6 man, machine gun bunker - STL

The Regelbau 630 machine gun embrasure was a bunker that formed part of the German Atlantik Wall coastal defence system during WW2. This model typifies the R630 design although variants were made. The bunker had room for 6 crew men and was prominent in the defences at Normandy and the D-Day beaches. These bunkers had multiple machine gun positions and were highly defended, often positioned with others of the same type in crossing fields of fire along the beaches.

This model of bunker had approx. 225 built during the war in various countries including France and Denmark. 35 tonnes of iron were used in its construction and 610 cubic meters of concrete were used in its construction with an average excavation of 400 cubic meters of soil

This STL file is designed for FDM Printers and print with a 0.6mm nozzle at 0.3mm layer height. Epic scale will require 0.4mm nozzle at 0.2mm layer height for best finish.

Supports are not needed for this model. At larger scales these bunkers may become larger than more common build-plate sizes. Please check the size below.

The printed model measures approx.:

348mm x 297mm x 84mm @28mm Scale

245mm x 195mm x 62mm @00 Railway scale

186mm x 148mm x 47mm @15mm Scale

75mm x 59mm x 18mm @Epic 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.

Print in place parts may need some work to loosen them up after print. Once free, run them through full travel several times to wear them in.
