Hàng rào tối giản Carrera 143/Go!!!

Simple replacement for the flimsy paper-fences/displays that come with some Carrera Go!!! sets. They fit snuggly into the original clips.

And yes, you really do not need to use the STL ;)
In your slicer, just drop a box from the Object Library onto the plate and resize to 185 x 12 x 1.2 mm. Two are needed for a 90° curve (just resize if you printbed is suffiently sized for a full 90° fence).

Can be shaped nicely when peeled off the bed while still warm.
