GT2 Pulley / Idler, 26 teeth for 5x12x5 Bearing (605ZZ) and 5x11x5 (685zz)

For 6mm GT2 Belt

Use 2 bearings 5x12x5 (605ZZ) for this Pulley

I recommend: a Layerhight of 0,15mm, / Speed: outershell 15, innershell 20



===== UPDATE 29.01.2015 ========
I found out that the 605ZZ with 5x12x5mm seems to be a chinese only product. You only find them on AliExpress. So I have added a STL with reduced inner diameter that matches on 685ZZ (5x11x5)
