Pentomino Starter Set

The puzzles in - https://www.thingiverse.com/thing:4206255 - "Simple and Difficut Pentomino Puzzles" are hard for some. Here is a "Starter Set" for beginning students - A pair of pentomino puzzles made from 2 sets of 3 pentominos: Puz_1_PUY and Puz_2_LNV. Each can easily be assembled into a 3x5 rectangle. The pieces can then be combined to make a series of puzzles that gradually become harder: a 4x5 rectangle, a 5x5 square, a 5x6 rectangle, and a 10x3 rectangle. See instructions below for making the other puzzles.
