Leveling mechanism for up to 4 extruders on Ultimaker. Takes only a few minutes to level. Once leveled it doesn't need to be re-leveled for a long time. The parts that clamp over your peek insulator should be made from Taulman 618 not Taulman 645; the modified 8B piece should be made of either type of Taulman nylon, But ABS might work for the 8B piece as well. Glass Transition Temp of Taulman 618 is 49.4 degrees Celsius, Heat Deflection Temp at 66 psi is between 170 and 220 degrees Celsius http://taulman3d.com/618-specifications.html. Nylon should be printed on whale brand TUFNOL to prevent warping (I would get 2mm thick TUFNOL (also known as Garolite (LE) )http://www.mcmaster.com/#catalog/119/3609/=oa3ba2. My first attempt was done with blue tape; while the parts still worked, they were warped very much, and so I do not recommend using blue tape. I found that a good way to cut thin TUFNOL is with sheet metal cutters. Here is more information about printing with nylon http://www.youtube.com/watch?feature=player_embedded&v=Klseu2xV68o.
If you dont want to use TUFNOL then you can try putting a layer of UHU glue stick http://www.uhu.com/en/products/paper-glues/detail/uhu-stic-klebestiftohne-loesungsmittel-1.html?cHash=568e237b4bf2f8dc0e7d33bc1a156a4e&step=1 glue onto kapton, this works well but not as well as TUFNOL.
Bowen clamps should be used with this leveling mechanism. http://www.thingiverse.com/thing:138502
