Making parts (Extruder module)
I'v already made hot end parts after the class of Computer-Controlled Machining. Another extruder module parts were made as follows.
Fan mounting
I thought about making most of body parts with aluminum.

But because I injured my thumb on my left hand few days after from I made the above aluminum parts, it became difficult to handle CNC machine. So, I decided to make other parts with 3Dprinter.

In that case, it is important to insulate from high temperature because the body made with 3Dprinter will be melt in high temperature.
I experimented that to insulate from high temperature by cooling with fan before. At that experiment, I could insulate from high temperature. So, I combined the fan to the parts I made with aluminum.

And using this parts, the experiment was done. Result was not good. Hot end temperature only increased to 270 ° C....
This problem was solved by raising the position to be cooled by the fan by 2 cm or changing heater cartridge from 80W to 120W.![](images/12/fanpos.jpg)

It seems well. But it needed a table to put this extruder module when it was not used. Then, I designed table for extruder .

I tried this exturder, it worked well, but sometime the pellet in the hopper may splash by the rotation of the drill.
