3D model description

For a newer and improved version on my own website, go to

Due to heat my extruder motors do not perform so well with long prints.
So I made these simple solutions for cooling them :-).

Because I have more than one printer and they are all slightly different,
I have 4 different models.
Also the fan size and model varys: see picture
Then there are 2 Nema17 motor sizes: see picture

The snail house fan works in opposite direction :-) That was easier :-)

Printed in PET-G
