I added 1 section of height to the screw section on either side of the arms, just split copy and pasted them on either side to increase the light bar to fit the higher z-height of the extruder after adding fans to the top of it with the Taurus v5 (and others) fan mod. It's not much higher but gives more room to print at a higher limit without crashing into the light bar especially if you have a diffuser on it.
The author remixed this model.
I raised the light bars by about ¾ of an inch or @19 mm. This is to fit the Taurus fan mod that increases the height of the extruder.
