Support for MG90S servo mounted on Reprappro Mendel extruder for auto bed leveling

thingiverse

This is a support for MG90S servo with a very smart stable arm see this very intelligent design http://www.thingiverse.com/thing:335203 mounted on Reprappro Menedel extruder. The purpose of it is auto bed leveling. I found out that the stability of servo's arm is critical for auto bed leveling. All other designs of servo's arm failed to be very reliable from the point of view of stability, but this one due to the mechanical stop (in construction of) assures I would say 100% stability and repeatability. Thank you Ralf for your design. Instructions The support is sandwiched between the fan and heat sink. The original design of the arm has a limited range of movement, and due to this I extended the profile hole on the primary arm in order to increase the range of movement from 30 degrees to 120 degrees. I did this modification by grinding the hole but as Ralf provided IGS file you can adjust it as you wish.
