Heavy Version NEMA 23 with 12 mm lead screw 🇬🇧

Thanks ! I plan to use SFU1204 so it will be usefull

Marco64 do you plan to modify the X & Y axis nut holder? That is all I see that needs to be changed besides the anti-backlash nut I already posted.

@streetdoc Yes, as soon as I checked the changes I will publish them too.

@Marco64 are you going to stay with NEMA 17 and T8 for the Z-axis?

@streetdoc I will stay with NEMA17 and T8 for the Z-axis. Only if there is a good reason to upgrade to T12 / NEMA23 I will do so.

I just uploaded the Y-axis nutholder for T12 to Thingiverse. Nut is fixed using M4 screws.

@Topsie For the T12 Nut holder of the X-axis to have enough space, the Y-axis Interior top pieces should be used that are named YAxis_InteriorTop_Right_NEMA23_T8_to_T14 and YAxis_InteriorTop_Left_NEMA23_T8_to_T14 right ?

However these pieces put the axis of the motor 11 mm more backward than the T8 version, right?  Is there a reason for this to be exactly 11mm ?
If it would only be 10 mm, we could use the T12 Y-axis nut-holder also for the X-axis. I hate to add yet another piece if it is not really necessary.

@Marco64, could we print a 1mm shim to move the T12 nut holder that far?

@streetdoc, I added a 1mm thicker nut holder for the X-axis to the Thingiverse thing of the nutholder: https://www.thingiverse.com/thing:4546903

I marked it with the letter 'X' to easily make the distinction between X and Y axis nut holders.

I corrected the X-axis nut holder on Thingiverse to make room for the screws that tie top and bottom together. Since the nut holder is larger than the original, there is some overlap with these screws.
