Sliding door floor guide

Floor guide for sliding doors, typically need two guides per door.

Redesigned as two parts to increase strength. Mine snapped off when knocked along a layer line. The new design is a push fit of the guide into the base from the underside. Optionally you can push filament through the hole to further secure the guide (I didn't need to do this).
