Very fun and challenging. I thought it would be easy so I increased the number of pieces from 20 to 30 in last moment...now I am making another one with 8 pieces :)
Its great fun and challenging! hard to put aside once you have found the first match -then it also gets easier!
-I glue them with minute glue.
Well it seems like one of the axis has been shifted, so you just need to turn the model 90 degrees around x or y.. the just press print / maybe scale by factor 10...
its made in unit CM..
Final should be 4x4x4cm
print area about 15x15cm
I now made three files with the 30 pieces distributed:
14 pcs on 'puzzleAlarge.stl'
14 pieces on 'puzzleBlarge.stl'
2 pieces for testprinting on 'puzzleCsmall.stl'.
But before you scale and test print file C, make sure file A and B fits your printer after scaling up.
