Malyan M180 Fan Holder

thingiverse

I started up my new Malyan M180, and the first problem I ran into was when I was about to feed filament. I just couldn’t get it into the extruder. The feeding mechanism could only be behind the fan. I started to dismount it with the result that I lost 1 nut and 1 washer (I did eventually find 1 on the floor and one under the heated plate). I am certainly not the first user to run into this kind of problem. Filament breaks, gets stuck and so on. So one has to be able to reach the feeder in a simpler and faster way. Who wants to dismount the fans when you have preheated the extruder for a filament change, just before you are about to print a new design. I don’t! My goal was to design a fan holder which allows me to dismount the fan without any tools. This is the result. One just snaps on the fan. Instructions: You will need 8 25 mm M3 bolts. Dismount the nuts and the fan grid. There are no reason to use this grid, it only causes extra noise. Pull the fan out, if you haven’t done it before be careful not to snap the cable to the fan. Loosen the tension on the extruder wheel. The screw in the upper middle is actually the axis for the tension mechanism. Remove the threaded axis, a good idea is to use 2 nuts that are tightened together. Now mount the fan holder with the M3 bolts, these bolts holds the extruder stepper motor so tighten well. And now just snap on the fan and you are ready to go. From now on any problem behind the fans can be fixed in a second!
