I love that extruder guide, it's one of the first upgrades I've printed and installed on my machine. After few months the base is now deformed in the thinner side, (said I've printed it in PLA+), so I've thickened it, and also made two versions. The original bracket is 30° angled by the cylinder. I've made another one 26.5° angled, it should resist slightly better to the ptfe tube.
Printing suggestions:
100% infill
0.12 layer height
supports
ABS/ASA

A bit thicker base, slight straight bracket
