3D punchbox for programmable music box

cults3d

I bought a so called " 30 notes programmable music box". It comes with few strips of card board and a punching tool to code the music with a succession of holes... Of course this is a really boring process ! I had to make it automatic using a small script in autoit which eats as input a midi file (single instrument file) and generates as output an openscad script nearly ready to print. see it here : https://youtu.be/SlEqRXkuC74 Read the video to the end as some user manual is inside. You'll have to download Midicsv.exe from here : https://www.fourmilab.ch/webtools/midicsv/ you'll have to install autoit from here : https://www.autoitscript.com/site/autoit/downloads/ and compile the 3Dpunchbox.au3 file or directly use the provided 3Dpunchbox.exe file (everything you need is inside the zip file)
