Balsa strip cutter / slicer

I don't see one that fits my need, cut 9mm thick wood planks, sturdy, precision, easy to use and also easy to print, so I tried to create my own. https://youtu.be/5J7KarZItto . This Balsa stripper allows you to cut a thick balsa planks(9~10mm) and adjustable depth(by turning the knob) from roughly 1~5mm(or 6~10mm from 2nd blade location). It takes over 6 hours for me to print and requires one M5 0.8 50mm hex bolt and 2x M5 nuts(other bolt/nut in similar size might also fit, like 10 32). You can
