A recreation of a fischertechnik giveaway from the 1970s.

Made with https://www.tripo3d.ai/ from a photo shared by Geert from the ftcommunity: https://forum.ftcommunity.de/viewtopic.php?f=6&t=8587&p=66327#p66327

The scale tripo3d chose is tiny, just zoom it to the desired height in your slicer.

To print this use Cura's rotate/lay flat function so that both feet touch the base plate, together with a raft for adhesion. Alternatively, move the model a tiny bit below the base plate (e.g. set Z to -1mm), this will cut a little from the bottom, but will result in a more stable standing model.

Use 2-3 walls, no infill, no support.
