In RViz and Gazebo, STL is displaced

Question

I am following ROS2 example for robotic arm. The arm has couple of parts, represented by STL. Now, when I use the STL file that comes with the example, the arm is perfectly aligned. But when I use Tinkercad (tinkercad.com), which is probably the best and definitely most popular of STL editors, the base I created becomes displaced:

The picture is for RViz, same in Gazebo. Any ideas?

Thank you.

I have found :) that Tinkercad saves selected STL WITH its on-grid coordinates, at least Z coordinate. In other words, before saving STL in Tinkercad, place it to 0,0,0. Very strange.
