What is a "Christmaspyramid"?

A Christmaspyramid or "Weihnachtspyramide" is an old decor piece from Germany: circular paterned candles create heat, which spins the propeller on top. The propeller is connected to one or more plates, on those you can find many different wooden figures.

What do I need?

You need one 608 bearing, measuring 7 mm (thickness) by 8 mm (ID) by 22 mm (OD). That is a classic skateboard bearing. I recommend buying a new bearing that is turning really well (ABEC 9 to 11). You also need 9 classical tealight candles (around 40 mm in diameter). Instructions for building: video above. You find the number of prints for each parts in the name of the part. You can print the whole set without support in case you have good bridging settings. If not you just need one support block at the end of the long rod.

CAUTION! Because this is all plastic, you should turn the candles off everytime you have used the pyramid. PLA has a low melting point. I made the design as save as possible. The Structure won't get hot, if you have a good turning bearing and exact manufactured parts.

If you have any questions feel free to ask in the comments section. The set is designed to not use any glue at all. In some sections it can be good to permanently use it. I designed the connections to press fit. It may happen that you have to use a hobby knife to adjust these fits depending on your layer height or your printer in general.

Design process

In total it took almost three weeks of sketching and testing the whole model. As a child I had a kind of obsession with these christmas pyramids. I had more fun looking at these than anything else! :D I read the book in my childhood and came back to it when i was 19-20. I am really glad that I had that relaxed childhood. Sometimes I want to return to that time, so that is why I made the pyramid spin counterclockwise. In case you want to use your own figures I have made a turntable with no connectors. YMost of the pyramids I have seen spin clockwise. You can make your pyramid spin clockwise by simply mirroring the turntable_cloud and _body_plane files.
