An assemble-after-print model of the Morf Worm: https://wonderworkstoys.com/products/morf-worm

The model is assembled as follows: 4, 6, 7, 8 (U), 8 (Box), 9, and back 9-1, both top to bottom and right to left, to make a crisscross shape (once printed it makes sense).

Regarding the downloads, each piece (4-9) needs to be printed 4 times. I made this easier and made a file that will fit a 220mmx220mm print bed that has 2 of each piece in the .stl and will only need to be printed twice.
