Tpu Guide Upgrade - Wanhao i3

This is an upgrade for the Wanhao i3 extruder assembly. This part removes gaps in the assembly that allow flexable materials to bend and get jammed. This part makes jams in the extruder far less frequent and also allows you to be able to print TPU faster without jamming. Steel is a higher temp alternative to aluminum, but it is heavier and may decrease you print quality by increasing the mass of the extruder.

I suggest this part be ordered with the polished metallic plastic, or  if you print above 220°C the aluminum material.
