Three Motor Z Gantry - Big Plans Printer System

These models are part of the Big Plans 3D Printer System: https://lilmikey.com/printersystem/ZGantry.html

Here is the gantry installed in an FT5: 

These models comprise a three-Z-motor gantry for completely automated bed leveling for cube style printers.  They use a ball and cup magnet system to allow for wide range of motion of the bad platform.

• Cap Magnet Mount - mount a counter-sunk 12mm round magnet to a 2020 extrusion.
• Corner Magnet Mount - mount a counter-sunk 12mm round magnet at a 2020 corner.
• Straight Magnet Mount - mount a counter-sunk 12mm round magnet along a 2020 extrusion.
• Triple Bottom Mount - Left/Right - mounts to the left/right lower frame extrusion and holds an 8mm pillow bearing and two 8mm smooth rod clamps.
• Triple Top Mount - Left/Right - mounts to the underside of the left/right upper frame extrusion (2020) and holds an 8mm pillow bearing (optional) and two 8mm smooth rod clamps.
• Triple Top Mount - Left/Right 40mm - mounts to the underside of the left/right upper frame extrusion (2040) and holds an 8mm pillow bearing (optional) and two 8mm smooth rod clamps.
• Triple Bed Mount Left/Right - carriage that ride along the left/right gantry threaded and smooth rods. Uses two LM8UU smooth rod bearings, one T8 threaded rod nut, one 10mm threaded ball/m4 boltand nuts.
• Triple Bed Mount Mid - carriage that ride along the left/right gantry threaded and smooth rods. Uses two LM8UU smooth rod bearings, one T8 threaded rod nut, one 10mm threaded ball/m4 bolt. This version allows the 2020 extrusion to pass between the smooth rods and is useful when you want a three rod rear gantry.
• Double Top Mount - mounts to the underside of the rear upper frame extrusion (2020) and holds an 8mm pillow bearing (optional) and 8mm smooth rod clamp.
• Double Top Mount - mounts to the underside of the rear upper frame extrusion (2040) and holds an 8mm pillow bearing (optional) and 8mm smooth rod clamp.
• Double Bottom Mount - mounts to the lower frame extrusion and holds a pillow bearing for an 8mm threaded rod and an 8mm smooth rod clamp.
• Double Bed Mount - Short - carriage that rides along the rear gantry threaded rod and smooth rod. Uses one LM8UU smooth rod bearing, one T8 threaded rod nut, one 10mm threaded ball/m4 bolt and nuts.
• 20mm T Joint - used for constrction of build platform.
• 2002 90 degree - used for construction of build platform
  Bed Plate Mount Offset - 2020 mount that takes m3 bed leveling screws - offset to one side.
• Bed Support Platform - 2020 mount that takes m3 bed leveling screws.
• Z Motor Mount - Basic 2020 mount for NEMA17 stepper with an offset tab for extra holding power. Can be used for belted or shaft mounted threaded rods.
• Z Motor Mount untabbed - Basic 2020 mount for NEMA17 stepper. Can be used for belted or shaft mounted threaded rods.
