Winkelturm - German Bomb Shelter

Yeah... this is a real thing. Designed and patented in 1934 by Leo Winkel, these 'Winkel Towers' were designed as a cheaper alternative to belowground shelters. After all, it takes less effort and material to just build something on top of the ground than below it. Between the first prototype in 1936 and the slowdown in production due to lack of resources in 1941, around 200 of these towers were built across the Reich. The concept behind the towers was that the highly-sloped sides would cause bombs to deflect and not directly explode on the tower, and in practice it proved to mostly work, but the thick concrete walls were determined to be too much concrete per shelter, so production was discontinued after 1943. About 60% of these towers were demolished after the war. The examples which remain are used nowadays for auxiliary tasks; museums, if lucky; storage, on average; one unlucky example was even converted to a Lidl sign.

There were sixteen types of Winkelturme which were built along the course of the war, the most common being the 1c, 2a, and 2c. 1c and 2c were of the shorter and squatter type, 2c having a mushroom-esque roof, and 2a is much taller and slimmer. 2a is the type which the current model represents.

This model is designed to be used in World War II wargaming, despite the fact that it looks like some sort of sci-fi Soviet fallout thing; I mean, you could use it for that sort of thing. It could also be used for gaming in Cold War-era divided Germany for a Cold War-gone-hot scenario, since the towers persist even to today. It is designed for FDM and is quite a lot of filament, but I suppose you could use resin if you had a large enough printer. Take care when removing supports around the internal ladders.

Designed for FDM, print somewhere around 0.2mm layers. Use supports!
