hi, found your fan mount, but after reading comments: is there more pictures to see of you printer? interesting...really..

You have a beautiful extruder gear. What kind of printer are you using?

Thank you! The extruder gear is from a old deskjet Printer ;-)
The printer that i use, is designed by myself :-)

Hahaha, wow, supernice. I have been trying to source parts from old printers for a long time, but in my country (the Netherlands) it is nearly impossible to get materials from the dumpyard after they have been delivered.
Right now my city is wanting to be a '3D-print' city, so I am trying to find out ways of getting the city council to cooperate with me and give me more freedom to move in and out of the electronic scrapyard et cetera because I think it can be a great inspiration for kids.
I'm also working in a radial cooling fan. Now I've made one, but it's cooling too good, so I have to make it 2 pipes coming out instead of just one. Right now the pipe is blowing too much on one side of my PLA prints, and this causes it to warp a little bit on that side, while if I spread the flow of air to come from 2 sides, I can let the fan run at higher speeds, causing it to cause less frequency noise (from the PWM) and it will cool the PLA better because it cools more evenly.
It's nice to see how everyone thinks differently about parts-design. You have the fan mounted sideways, I have connected it to my vertical X-carriage as some sort of a 'backpack', that hangs on a frame. The frame is then connected with 4 tie-rips. The tie-rips go into the X-carriage and also secure the LM8UU bearings at the same time. It was important for me to add a solution that didn't require 'yet another set of bolts'.
Right now I'm working on a new direct-drive bowden extruder, but I might also go back to using a standard non-bowden direct drive because I notice that my printer doesn't print well at high-speed anyway.
