For the model, it is a number slide puzzle. So it's a tile with numbers 1-8
and 1 blank spze and you try to move the numbers and get them in order... but with a twist!
The pieces only move in one direction, indicated by the piece itself. All the outside
pieces can twist to move any direction but the middle piece can not twist. So with this in mind,
try to get all the numbers in order and in the correct orientation. To make, I printed the ALL
file that has all the pieces to print in the correct orientation. I printed in PLA at .16 layer height.
However, For beter results, print out the number pieces seperatly and change color at height of .3mm.
then, slide all the numbers in from the open part. The top left corner of the board (the one with the hole)
is where #1 goes. Slide the pieces in from the bottom in the correct order so they display all the numbers
in the correct order and in the correct orientation. Then glue or attach the endcap on and scramble!
There is also a board with extra tolerance if you need it.
