Hot end cooler for Solidoodle2 by m4rten86

Last crawled date: 3 years, 1 month ago

This is an invention to cool down the plastic that comes out of the hot end with cool enviromental air ( room temperature). This is very good for printing small objects faster. Also I experienced that it's possible to print about 30mm in horizontal direction.
So you can setup the bridge distance in slic3r to a bigger distance and it's easier to remove these after printing :-)
The electric controll is based on the Gcode conrolled Fan Mod of Ian Johnson (http://solidoodletips.wordpress.com/2012/10/26/gcode-controlled-extruder-fan/)
but instead of a Fan i used a relais that switches an air pump for aquaria. there are really cheap ones for only 10Euro ( about 13$).
I designed the Tubes (i wasnt supposed to look like .... ! :D ) and they really fit very well with a glue simply made of Aceton and ABS plastic.
Also it looks good when you paint them in copper or iron colours. ;-)
