Luthier Radius Blocks

These are radius blocks often used in forming the proper curve on guitar fretboards. Large blocks are 8" long (203.2mm) and the Small blocks are 4" long (101.6mm). The width of the blocks are 2-3/4" (70mm). Attach some 80 or 100grit sandpaper to the bottom of the block and sand the fretboard to a specific radius.

These blocks are very rigid when printed with an infill of 25%.
