-As with the built-in rounding arguments, you can use [edge\_mask()](https://github.com/BelfrySCAD/BOSL2/wiki/attachments.scad#module-edge_mask) and [corner\_mask()](https://github.com/BelfrySCAD/BOSL2/wiki/attachments.scad#module-corner_mask) to apply teardrop roundings using [teardrop\_edge_mask()](https://github.com/BelfrySCAD/BOSL2/wiki/masks3d.scad#module-teardrop_edge_mask) and [teardrop\_corner_mask()](https://github.com/BelfrySCAD/BOSL2/wiki/masks3d.scad#module-teardrop_corner_mask) to limit the overhang angle for better printing on FDM printers. Note that the vertical mask on the RIGHT_FWD edge is a rounding\_edge\_mask().
