Replacement Lower Guide Plate for the Truvativ X-Guide Chain Guide

This bicycle part is intended to be a replacement part for what's called the 'Lower Guide Plate' portion of the Truvativ X-Guide Chain Guide. The function of this part is to guide a loose chain back onto the gears should it come loose. Because of its position on the bike it is prone to failure. Unfortunately Truvativ has not made replacements widely available for this non-essential part.

Tested using Makerbot Thing-o-matic using ABS plastic.

Printing Notes

This design has a hole for a 2.75mm screw. However, it is also recommend that you print with some 1 or 2 shells as normal use for this bike part can be pretty stressful. This can make fitting to the screw a little challenging. Four versions of the stl file areincluded with varying hole sizes. You can also modify the HOLE_RADIUS constant in the SCAD file to your liking.
