When printing for some time the motors get hot. I do not like that. I looked at some designs for fans mounted to the motors, but they only did the X and Y motor. With this solution you can do the X-,Y- and Z- Axis and bring the heat outside of the printing area

Find some old laptops and remove the heatpipes I used 2 old broken HP nc6120 and one broken HP nc 6320 because they have copper heatpipes.
Because of the available screws I had to widen one of the holes. Furtermore I have bent a small ridge outwards.
The right hand side motor is the most easy. Drill a small hole in the frame for the right screw and a larger one for the screw on the left. The fit is good and the heat gets transported outside of the frame. (I have added some distance blocks to protect the heatpipe)
The left hand side is more complicated. The headpipe needs to be bent to avoid blocking access to some switch screws. The connection to the motor is also less than with the right hand side motor. This can be fixed by using the paste that is used with ICs
The Z-axis motor is very comparable to the right hand side motor. Fixed with just 2 screws.
