Just another two hour project: BRIO flex tracks
I used simple boolian operations on a standard BRIO railpart in tinkercad to make it flexible in all direction. Printing with a fast “single-line” stategie on Desktop FDM 3D-Printers – each piece takes as little as 20 minutes to produce.  When printed with the superstrong PLA-Hi from creamelt, those BRIO flex parts become indestructible.
