About this 3D model

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
