12 inch radius guitar fretboard sanding block

thingiverse

I was about to order one from the Far East, but then a more efficient solution came to mind. I'll print one in just a couple of days and share my findings with you. The design was created using AutoCAD software. Update: I printed it on its back, which didn't quite work as planned. Perhaps standing it up on its end would be a better approach. It took nearly two hours to complete the task in draft mode.
