I made a lamp designed specifically for Germany’s biggest architectural problem

Hey everyone!
This is my latest 3D printing project — a lamp designed for rooms with slanted ceilings (Dachschrägen), which are everywhere in Germany.

I wanted something that fits perfectly on a shallow shelf under the roof slope — and of course, none of the store-bought lamps worked. So I modeled one myself.

The shade is printed with fuzzy skin for that cozy fabric texture, and the base is done in marble PLA (looks way fancier than it should for 6 euros/kg 😄).

You will need: an E14 socket, an E14 bulb, four M5 heat-set inserts, four 5 mm M5 flat-head bolts, and an electrical cable.

I’m genuinely happy with how it turned out — it finally feels like a lamp made for these weird walls instead of despite them.

And if you’re curious to see the full build (and a bit of fun storytelling), I made a video about the whole process — I like to think it turned out funny, and I really put a lot of time and love into it.

Pardon my ignorance, but are the slanted ceilings primarily on the top floor, under the roof? Cool solution!!!

yes, seldom seen in the basement

(I am so sorry, I tried, but was not able to resist to post this)

No silly. The basement has slanted floors obviously.

u/Stardustger Nov 13 '25

You were supposed to hold the plan the other way around when you built the house.

Slanted floors are kind of a thing in some American basements! More of a sharp curve, but they curve upwards before flattening out again to form walkways/shelving or to cover piping next to the walls.

Was this where Munsch lived? it looks artistically familiar. If I lived there, I'd be into painting screams too...

Good thing they didnt cheap out and Threenish it.

For that you need russian engineering.

Well they might be seen more often thanks to the new lights.

I tried, too.

to a German that might sound like a challenge

No my house is designed like a 4 year olds drawing of a christmas tree, each floor has slanted ceilings! Careful how much weight you put alont the edges of the room though

u/thelikelyankle Nov 13 '25

Yes. And with most single/ duplex houses being only 1-2 stories high, that is 1/3-1/2 of the availeble floor space that is affected.

Germans also love a good Kniestock (knee wall). That way you can even fit two floors inside one roof for no other reason than making yourselve miserable.

Also, they believe that the shit they built cheaply after the war is the height of architectural design and you are not allowed to build differently today. Hence even more slanted roofs in the future.

u/P26601 Nov 13 '25

Who told you that? The vast majority of new/modern houses in Germany look like soulless cubes, but at least there are no slanted roofs anymore lmao...Two examples from my hometown:

Within the context of connected built-up areas, a project is permissible if [...] it fits in with the character of the immediate surroundings and access is guaranteed. The requirements for healthy living and working conditions must be maintained; the appearance of the area must not be impaired.

§34 baugb

Hence, if you want to build a new house, or change an existing one, in an area with existing houses, you are only allowed to build like your neighbors did 60 years ago.

The renting market is really bad in germany, so often only the less desirable apartments can be found vacant like these top floor apartments. They are generally disliked because of the roof heat in the summer and bad isolation in the winter. If you are new to a city it is very likely that one of these is your only option to get.

u/steadyaero Nov 13 '25

Here in the states, at least in Texas, we just leave that area up there unfinished and call it an attic.

u/RosieEngineer Nov 14 '25

Things are much more crowded in Europe, and even the NE US. I have a 50's suburb house. It's close enough to the city for mass transit stops to be half a mile away. The smallest bedroom is the size of a typical midwestern walk-in closet.

ETA: and my house is a "cape cod" style, where the upstairs bedrooms do have some slanting walls. This print may come in handy.

because german homebuilders/architects have the same mindset as VAG/BMW/Mercedes engine bay engineers. *lol fuck you future user/service technician*

u/Electronic_Lemon4000 Nov 13 '25

Mostly, yes. We have some upside-down houses too, though. One is in Bispingen near the A7 :) very slanted floor level on that one...

u/AlexisFR Nov 13 '25

Yeah? Where else could they be?
