Cello Endpin Nut

I made this because a couple cellos in my classroom had missing nuts and the endpins were falling into the cello. Instead of buying replacements I printed these and they worked great, There are two versions here. One is larger and rounded at both ends. One is flat on one end if you want an easier print and for it to sit flush with the instrument.I've tried 0.1 and 0.2 printing. and both work well.
