Understring Fret Leveler

thingiverse

This is a fret leveler you can use with your stringed guitar or bass. It was inspired by [StewMac's Fretbar Understring Leveler](https://www.stewmac.com/luthier-tools-and-supplies/tools-by-job/tools-for-sanding/stewmac-fretbar-understring-leveler.html) with some modifications for easier printing. I modeled it because I needed it quickly, but if you like it, please support the original designers by ordering a much higher quality aluminum version from StewMac! You can use a 1" 3M sandpaper stikit roll, or double-sided tape and normal sandpaper cut to size. This version is 1ft (30.5 cm) long, but you can scale it to whatever your print bed size/height is. I also included a "string jack" that lifts up the strings for easier sanding of the lower frets. I recommend you print this one in TPU or other flexible material.
