get creative , where i guess it ain't that hard to get the design made in Solidworks or cad . I lost the PC with all my files and working out how to draw a new digital file that for instance a laser-cutter could use . There is a good wood laser cutting company not far from me , when i have some cash and the file i will order a 3mm multiplex one there .
Everyone is free to make there own , me claiming anything is a bit of a joke and like wanna get rich from ductape and banana's . But very mach appreciated when i get linked to come and see what others made of it ,.. and , if they can solve it .
Where if someone went full commercial production on the puzzle aspect i would not mind to get some minor profit from it . Where i don't no if the ghost of Escher can claim some profit to . ;-)
Have some fun i say , be creative , share it engage it .
