Laminate Flooring Edge Guard

I created a floor mat for my office chair out of laminate wood flooring to protect the carpet, and needed a way to protect the exposed edges of the laminate.

This particular guard is design to fit into click-together flooring with a center groove, specifically Home Decorators Collection EIR Laminate Flooring (model # HDCWR19).

Corner pieces may be generated by guardType to LEFTCORNER or RIGHTCORNER in the OpenSCAD file.
