filament guide lack enclosure pc4-m6

My first own build of a filament guide for the ikea lack enclosure. There is a moint possibility for a pc4-m6 to connect your PTFE-Tube. The output is conical to avoid the sound in the top of the lack enclosure. 

You need to drill a 20mm hole in the top part of the enclosure and for maximum silence it is better to glue it into the top. 1mm distance to the top of the case is perfect.

Hope this will help somebody!
