This is only experimental for now. Maybe somebody will get a good idea from this thing.

I get my basic idea from https://www.thingiverse.com/thing:724999.

• Thing name changed from "Experimental linear pipe rail" to "Experimental CNC"
• Added parts for pipe corner connection
• Added legs for pipes
• Added some pictures

Update 8 Oct 2017: https://youtu.be/2t07-q1Qufs

• File names changed to english
• Added upper and lower connect stl files
• Added some pictures
• Updated settings: Infil to 70% and Resolution to 0.2 (much better results)

Update 23 Sep 2017: Added "cevni tir v3.STL" it has holes at the bottom. I started to draw some connections parts to connect two of this pipe rails together and for connecting other pipe for other axis tho this mount. Looks like i will updating this thing regularly.
