An easy way to keep your Extruder motor cool :-)
Temperatures are high if you print with ABS or PET-G.
The extruder motor is always in a hot environment and that is very bad for its performance.
if your printer is in a enclosure, then it is even worse :-)
I found it's good for performance to active cool your extruder motor if it is in these conditions.
This cooling solution utilizes the fan normally used for active cooling of the printed part.
One model supports the "X wagen cable holder" solution (another model of mine).
The other model is for people who do not use the "X wagen cable holder"
In the real pictures you can see the one with the X wagen cable holder.
