Update 3/13/17: Added Couple Photos. Note that for Y Spacer, Also Added Piece on Lever of Microswitch with Shrink Tubing. Had to Move It Farther Forward to Avoid Hitting Clips with Fan, and Shrink Tube Was a Faster Option for Me. Notice That Switch Is Moved to the Farthest Forward Location on Frame. Time to Print New Spacer, Scaled to Make It Taller. Update 5/16/16: Added Shorter X Axis End Spacer to Position Single Extruder Close to the Edge of Plate. If Dual Extruders Are Used on an E3 Mix Nozzle Base, the Left One Is Outside the Print Bed. As I Learned After I Posted the Original, the Dual Extruder Nozzles Are Best Handled by Telling Software/Firmware That They Are Located at -Xmm and +Xmm, Leaving Nozzle Centered and at Zero When a Mix Extruder Is Attached to the Machine. Note: The X Axis Spacer Is for the Metal X Axis Plate That Supports Linear Bearings and Extruder Holder in the Current Version of the Geeetech I3 Pro C Printer. The Y Axis Piece Can Probably Be Used on Other Acrylic Base Plates. When I First Got My Printer Running, the Home Position Was Outside the Printer Bed. I Tried to Get It Working in That Position, but Was Continually Frustrated by the Extruder Banging Against Clips That Held Down the Glass When It Started to Print. I Made These Mechanical Spacers So the Home Position Could Be Positioned Close to the Origin of the Print Bed, on or Near the Glass So It Would Avoid Collisions with the Clips Holding the Glass Plate. The X Axis Piece Is Retained and Stabilized by the Screws on the Metal X Axis Plate. The Y Axis Piece Was Attached to the Print Bed with Double Sided Tape. The Y Axis Piece Is a Bit Longer Than I Needed, but I Moved the Microswitch Back a Bit to Make It Work. It Could Easily Be Shortened by Scaling in the Printer Controller Software (Repetier in My Case) or by a Subtractive Machining Method (With a File, Sandpaper or Grinder). Print Settings: Rafts - No; Supports - No; Resolution - 0.4 mm nozzle, 0.3 mm layer height; Infill - Not Required. Notes: I Printed These in PLA and They Were Functional. The X Axis Piece Is More Delicate, and ABS Would Provide More Durability. Post-Printing: You May Need a Round File or Drill Bit to Make the Holes Fit the Screws. How I Designed This: Sketchup
