Regelbau B1-1a Small German MG Embrasure Bunker - STL

These bunkers are so-called MG embrasure stands; the crew size was 5 men. They were accommodated in fold-away beds. The main weapon was a machine gun on a table. An MG with a plate mount was planned for these bunkers, alternately an MG 34 on a gun carrier. The armour parts of the structures are primarily the plate, behind which the MG stood. The plate has a weight of 7.5 tons, is 10 cm thick and has the dimensions (width x height in cm) 370 x 270. In addition to the opening for the MG, it also has a viewing slit. Both could be closed with a slide. The slider for the MG slot has a thickness of 6 cm. 

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, you may need to cut them into sections for your machine. Please check the size below.

The printed model measures approx.:

180mm x 154mm x 65mm @28mm Scale

118mm x 93mm x 44mm @00 Railway scale

90mm x 71mm x 33mm @15mm Scale

36mm x 28mm x 12mm @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.
