These have now been printed and tested for the Z and X Axis.
The X axis will also require an additional part that I am going to have to model and make in the next few days so stay tuned for that.
These are brackets for endstop switches for the QU-BD Two up 3d printer. These take into account the newer models that are coming with the shaft coupler.
You will need the following hardware and modifications in order for these to work.
The X Axis requires either the modification of the part "N" to clear the bolt holding the X Stepper or removing that 4th bolt completely (Bonus of about 15mm build area!)
The "Z trigger" will require a #8 screw be drilled into the X Gantry. I had to remove the bottom portion of Part "O" but no structural integrity was lost. (we all know how flimsy the gantry is)
Two M3x0.5 x 20mm
Two #8x 1" Screws
3 Endstop switches with 0.75" Mounting holes
03/31/15: Initial Upload and test
04/01/15: List of parts and mods added. Z Trigger Updated to be shorter and allow for better adjustibility
The holes are made to work with the standard endstops that you can buy on Amazon or Ebay.
The Z trigger is either drilled and screwed to the X gantry or super glued in place. A #8 bolt and nut is used to change the trigger point.
The Z backet uses the left 2 most screws on the z stepper motor.
The X bracket uses the 2 left most screws on the x stepper motor and may need longer M3 bolts.
