Using a Bachi on bass guitar?

Hey all, I recently researched this instrument (along with Biwa and Tsuzumi drums) for a university class and for my video I tried to model how players would strike the strings of the shamisen with a bachi by using my fretless bass and a flat rice cooker spoon. It strangely sounded kinda good so it got me thinking about using a Bachi or a similar plectrum. The main issue is that I feel using a wooden plectrum with metal strings wouldn't work very well, are there plastic makers or ways to 3d print (a friend of mine owns a 3d printer)? I wouldn't want to destroy a valuable bachi for an experiment lol.
