Hide all but Basic shapes menu and togle sidepanel with F12.
This script Hides the search and extra menu in Tinkercad, so the Kids in a classroom are forced to draw somthing for them self with the basic shapes!
ALso with the F12 function key you can hide the menu panel for more workspace.
I use this in a puplic library makerspace where we can 3D print the objects with Bambulab A1 printers.
