And a big thanks to Ultimaker for the published STEP files I could use to take the measurements from!!
update: 30/6/14 > added a little knob for easy spring adjustment (see last picture)
update; 2/7, as cor3ys already mentioned in the forum the arms holding the bearing are a bit to short (sorry, I only tested at low speeds...) updated the file. Version nr. 25 of the front and back arm have 2mm increased length.At the same time made a little change for easier installing the m3 x 50mm bolt...
Materials and methods
some M3 bolts
I would like to use a long m3x60 hex bolt, but could not find one... took a (non hex) m3 x 50 bolt and placed a normal hexnut on it with "bison lock bond" to make a hexbolt....
