Replacement Violin/Viola Shoulder Rest Nut

thingiverse

My son has finally lost one of his shoulder rest nuts, prompting me to create a replacement. I found Ace Hardware sells the necessary nuts for just ten cents each, although there's likely about two cents' worth of plastic in each piece. These nuts work beautifully and save me from having to purchase an entire new shoulder rest. The specific nut required is a hex 6-32 model. During my initial test print, I had to increase the scale by twelve percent before achieving the desired result. When printing without pausing for upscale, the printer successfully inserts the nut at 7.6mm and then prints additional plastic to secure it in place. However, when including an upscale pause, the optimal print height is 8.5mm. So far, I've successfully tested this design on Kun shoulder rests with outstanding results!
