E Step Filament Guide

2 part filament guide, the top mounted piece is a standard guide from the reel to the lower (part A) guide. the lower guide guides the filament directly to the extruder but also doubles as an E-Step measuring tool.

To use the E-Steps measuring tool take a length of filament and make 2 marks 100mm apart, align the first mark with the indicator near the extruder then mark the guide near the end were the other mark is on the filament. Now when checking E-Steps all you have to do is mark the filament at the top mark on filament guide A then extrude 100mm and the mark on the filament should be at the indicator on the guide.
