British Type 25 Pillbox Fw3-25 - WW2 Bunker

British Type 25 Pillbox Fw3-25 - WW2 Bunker - STL

The type 25 pillbox is the only FW3 design that is circular, with a diameter of 8 feet (2.4 m). The walls were just 12 inches (30 cm) thick with no internal walls. There were three embrasures suitable for rifles or light machine guns and a small entrance like a low window. This design was made from reinforced concrete shuttered by corrugated iron; this gave the design the popular name Armco after the manufacturer of corrugated iron of that name.

The type 25 is rare: about 30 are recorded as extant.

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.:

50mm x 50mm x 42mm @28mm Scale

32mm x 32m x 28mm @00 Railway scale

25mm x 25mm x 21mm @15mm Scale

It is designed for 28mm table top games set in WW2 such as:
