Rubber band powered guitar with pick

I designed 3 mini guitar that work using rubber bands .

There's 3 different versions with different rubber band length so you can find a version that fit with the rubber bands you have.

I also created a small guitar pick

Each guitar are 231mm long but that be scale as needed

Print settings:

Layer height: .20mm works great.

2 walls, 15% infill. 

STL are oriented the best way, so you won't need any supports.
