Regelbau R654 anti-tank 5 cm KwK embrasure - STL


The Regelbau R654 bunker is a large concrete emplacement/embrasure for a 50mm KwK anti tank gun and was build in several places in the German Atlantik wall of WW2. Notably in the fort at Saint-Nazaire in France. The bunker contains a room for the anti-tank gun, a ring-stand for an observer or machine gun post, as usual with German bunkers the entrance is covered by 2 secure internal MG windows and there is a large ammunition storage room. The used shell casings are then ejected through a small chute in the wall to a collection pit to the side of the gun room.

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.

At 28mm scale this model gets very large and may not be printable on consumer standard machines in a single piece, please see dimensions below. You may cut this model into sections for printing as required using 3d builder.

The printed model measures approx.:

366mm x 236mm x 85mm @28mm Scale

240mm x 155mm x 55mm @00 Railway scale

183mm x 118mm x 42mm @15mm Scale
