Servo Mount for MendelMax 2 Auto Bed Level

thingiverse

Description This bracket affixes a standard micro-servo to the MendelMax 2 hot end carriage, using the front two mount points to allow an extended armature to raise/lower when using the Marlin auto bed level feature. The arm affixes to the front edge of the carriage and moves in a vertical plane aligned with the hot end nozzle, making setup easier even with other mods in place to either side. This design prints without support with the servo socket oriented to the build platform, while both ends are left open with skeleton frame ribs to ease routing the contact sensor and servo wiring around the hot end. Print at least 25% infill for durability, 2 shells. Instructions In order to demonstrate 3D design of printer components and add-ons for my students, I took measurements of the front carriage spacing of the MM2 and a spare micro servo and then simply built the design using the free in-browser TinkerCAD. The Arm was adapted from ZenMaster's z-probe design.
