Note: The person in that video is being a bit weird with it. Just strum the strings like a guitar & all the pasta will immediately fall down.
What you'll need to make my pasta guitar:
Length of 1"x4" wood
2x of the STL found in this listing
Optional: 4x [Pasta Guitar Wood Peg.stl]
Assembly:
Print 2x [Pasta Guitar V3.stl]
Optional: Print 4x [Pasta Guitar Wood Peg.stl]
Cut 2 lengths of your 1x4 to whatever length you want for your noodles. 14in should be fine.
Slide the 1x4's into the slots on the STL you may need to shave/trim the wood to make it fit. I just measured a random 1x4 I had in my shed for size (the slots are 18mm x 88mm).
Drill the holes found in the STL using a 1/4in bit.
Either secure the 1x4's using screws or tap in the pegs you printed using a hammer
