Regelbau R630 Large MG embrasure – 3D printed model


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 is a multipart model and is printed in PLA


The 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 Warfare


The outside of the bunker is a replica based on plans and source material, the interior has been edited to make the insides usable at scale, the walls are not 2.5m thick to scale for example. The 28mm version has been adjusted to allow bases to be placed in all rooms.
