Some time ago it was discussed in the group what exactly was meant by a 10
x 10 cm object that the rider has to clear as a requirement for level 3.
I have now made such an object from plywood and antislip rubber. The
height can be adjusted in small steps from 1.0 (via 10.0) to 11.0 cm. This
has already proven to be very useful for practicing, i.e. once you get the
hang of a particular height you increase it by a small amount.
