Filament Guide - No More Gap

Love the original model, it was exactly what I was looking for. Unfortunately with a modest retrace, the filament would come loose from the bearing guide and nestle itself firmly in-between the bearing and guide, getting stuck in the process. This variation has slightly thicker walls just below the bearing wheel to close the gap.

'Twas a crude modification. But it works

Closed the gap that filament got stuck in.
