This set includes alternative models (not included in other sets) of 17 most common point groups, which are all crystallographic (the same point groups as in the another 17 item set). This set is very handy for taking exams as it does not contain tricky molecules and you can keep it in secret for students until the time comes. For that reason, one can use two sets: the
42 item FULL set 3D printed in white plastic (as it is cheaper) for general practice (as the 42 item FULL set includes a few difficult to perceive example molecules), and the 17 item ALTERNATIVE set 3D printed in a different color with respect to other sets for taking exams (so that the models are easily distinguishable between the sets).
The set includes models #a1-#a17.
