I’m quite exited to get to test this. I don’t have experience on shamisens yet and my Shamisen quide is still in post office waiting me. But heres my project so far. I’m missing strings but will pick them up soon, planned to start with nylon guitar strings as theyre easy to aquire. Printing the parts is done. Model was made by Dysanius. I first was planning to edit the model little but soon found out that it is easier to go with the plan at start.
