This is a Heart shaped puzzle using Tetris pieces.
Every piece is a small building generated using a remix of my Futuristic Cities and Sci-fi Cities algorithms in OpenSCAD.
heart-pieces.zip : full set of the 24 STLs needed for completing the puzzle.
frame.zip: STL's for the frame. (frame.stl->Full frame and frame1/2/3/4.stl for the splitted frame if the full frame doesn't fit in your printer bed)
frame/frame-split.123ddx :123DDesing files for the frame. Feel free to modify and made your own frame.
Unzipped STL's : a full set of pieces generated using Customizer
You can use the Customizer for generating new random full sets of pieces (one piece for every possible shape including 1-tile,2-tiles and 3-tiles shapes)
In the Customizer you can set the tile size (In examples i've used a size of 20mms) and generate sets of pieces of any size.
The puzzle it's not very difficult to solve but is quite changelling. There's many possible solutions, just like the Pentominos but using 4-tiles pieces.
Hope you enjoy it
ANET E10 / Creality CR-10
No special settings, easy print. It takes around 30-60 mins per piece and 90-120 mins for printing the frame.
For the 4 pieces of frame i've designed the connecors with high tolerance to avoid problems fitting the frame.
