Add missing&extra parts, & unofficial & official documentation. Note CAD model errors.

[Poikilos]

Added

• Alternate bed screw spacing parts
  • 206mm spacing on Y: alternate Z component jig
  • 206mm spacing on Y: alternate bed carriage uppers with necessary reach
• Alternate z leadscrew block for anti-backlash POM lead screw nuts.
  • In the only assembly video I could find, Voron Legacy by Fugatech 3D Printing on YouTube, he didn't provide a link to his nor reply to my comment asking for a model, so I remade it (tested, installs fine).
    • Fits "Ender 3 V2 Z axis T8 POM Anti Backlash Spring Loaded Nut Elimination Gap Compatible with Voron 2.4 Ender3 pro 3D Printer 8mm Acme Threaded Rod" from POLISI3D Store on Amazon.
    • I added a note saying that they are consumable and that the sourcing guide recommends regular brass ones.
• Link to Blend file with all of the above (over 100MB GitHub file size limit).
  • Committed all exported STL files listed above to git.
• Link to an unofficial assembly video.
• Link to forum administrator's "Brief assembly guide"
• Link to my (WIP) unofficial assembly manual.
• Add missing y rod alignment jig (from Discord, originally named "legacy_tool.stl", by deleted user)
• Add "Stealthburner with CW2" X carriage parts (from Discord, credited Ibbanez VL.029)
• Add FreeCAD file

If anyone can help, the following issues need to be fixed in the STEP file (done in blend file) but I do not have Fusion 360 (my business' income exceeds the amount in the personal use license):

• Edit end of A & B motor shafts so they are 24mm from the screw surface like motors in the 1.6.2 BOM: 0.152 longer (to match 24mm distance from screw hole surface like motors in 1.6.2 BOM)
• Move gearheads in CAD file(s) to their correct locations (See my blend files on Google Drive which have the belts centered on the idler pulley pairs):
  • Move A (right) gearhead (20T pulley) down by 2.35 so it is out 3.45 less than end of motor shaft
  • Move B (left) gearhead (20T pulley) up by 0.10217 so it sticks out 1.25mm more than end of motor shaft
• Add missing part names
  • inductive probe
  • See changelog 2025-07-26 for more
