2-Piece Drawer Runner replacement

Simple replacement runner for wood drawers. 320 long X 15.7 High X 8.5 Deep. I have a good set of pine drawers completely ruined by cheap nasty plastic sliders which keep breaking. So printed my own far superior one's.

Manufacture in two parts as my bed isn't big enough to print in one piece. They slot together to aid alignment you could glue them but there's really no need to.
