   I am wanting to experiment with different designs for the idler that is in the titan. What type/size of bearing does the current idler use against the filament?

   The bearing is on a 3mm shaft, its 4mm thick, and has 10mm outer diameter.
   
   This is a 623 bearing.
   
   You can look up bearing sizes on charts like this: http://www.smbbearings.com/products/miniature-bearings.html
