The material for the profile is standard aluminum, 20x20 dimensions are expected from a certain source but I will accept approximate equivalents from a different one since adjustment can be made using the oblong holes. I plan to use bearings of type 608zz and four basic gauges with diameters similar to 29mm. Additionally, you'll need ten pieces of plastic bearing rollers sold at http://www.aliexpress.com/item/10pieces-626zz-6-27-8-5mm-pom-bearing-Shower-Door-roller-runners-Wheels-plastic-pulley/32260468103.html?spm=2114.01020208.0.456.AD7rgK for a price I've found on that web site. I'll also be needing four long M5 screws with self-locking nuts measuring 40mm, two smaller ones measuring M3 for the maintenance of a certain belt and one additional 608zz bearing to fit within a specific clearance. To facilitate adjustment, I plan on using bearings of type LM8UU and others sold at http://www.thingiverse.com/thing:540716 with cone fan duct also bought from this source. I have reviewed all my expectations to include every part needed for your task but in case I forgot anything you can reach me if that's the case.
