Inspiration for this design goes to AzzA's Z Extensions.

First off, I do not know if these will work with any other Z brace other than the GulfCoast Robotics Front Mount Z Brace kit, as this is what I have on my Maker.

The original AzzA Z extensions worked, but there were some things about them I didn't care for:

1. There were 4 visible hardware holes after moving the crossmember up.
2. Those 4 hardware holes were not being used that were before.
3. The Z-rod bracket becomes improperly positioned after the mod.
4. The side tab of the crossmember was tweaked/improperly aligned with the gantry after the mod.

So, I set about resolving all of those issues, and this is it.

No more visible holes, all the hardware used, Z-rod bracket and side tab both properly positioned.

If you've previously installed the AzzA Z extensions, you will need an additional 4 each M3 x 8mm socket head cap screws and M3 Nyloc nuts.

If you are working from a stock machine, you will need an additional 8 each M3 x 8mm socket head capscrews and M3 Nyloc nuts.

There is only 1 Z extension, a Right hand version. Add and mirror a 2nd in your slicer.

Don't forget the 2 spacers: 1 for each side.

I've included STL, STEP and SLDPRTs of the Z Extension and the Spacer.

If you would be so kind, please Post your Makes.

Thank You.

.15mm

50%+

These were sliced in Cura 3.6.0 and printed with eSun PLA+ at 80mm/s, 220°/60°, Support Everywhere, 50% infill, 3-line Brim, 50% Fan after Layer 1.

My preferred print orientation on the bed is shown in the pictures.

I drilled out all the holes with a 3.2mm bit from the backside, then pried the remaining support out from the front.

The slots pry out easily: ream them with the 3.2mm bit as well.

The 2 spacers fit between the gantry and the Z rod bracket on either side.
These ensure that each Z rod bracket sits flat as in the stock placement.

Install all hardware loosely, then tighten.
