Ender 3 Pro T-Bone Z Bracket

This bracket allows a sprite extruder with a 0 y-offset probe to travel over the bed screws for assisted leveling and a greater print area. I also had a loose x rail so I moved the eccentric spacer hole closer to the rail by 1 mm for a better grip. Your mileage may vary. 

The carriage will probably hit the belt tension bolts before hitting the bracket. I set my x stepper max and right bed screw x position to 244 mm in klipper to avoid this so it's probably still 1 mm off.

Printed in PETG with 100% infill. 20% was definitely too flexible.

Cut away excess material and moved the hole for the wheel on the eccentric spacer closer to the right Z extrusion by 1 mm.
