RatRig V-Core 3.1 400mm Rear Electronics Panel

Improved electronics panels for the VC3.1 400mm to enable mounting of additional PSUs (2x Meanwell LRS-200 or 350W equivalent and 1x Meanwell LRS-150 equivalent), dual SSRs (bed + chamber heater), and fixed mounting for a Raspberry Pi and Octopus with quiet 120mm fan cooling for the Octopus and stepper motor drivers.   With aluminum mounts for all major components, your electronics will remain solidly mounted.  Using M6 roll in nuts means easily taking off components in the future if you ever need to replace them.  No holes that go through the panel into the chamber mean a superior seal on the chamber and less holes for heat to escape through.  Larger 40mm center cable guide and several larger 30mm horizontal cable guides provide more space for cables and more organization for clean wiring.

I honestly don't recommend most people do this mod due the complexity of replacing the rear electronics panel, but wanted to upload it in case someone else does need it, still has yet to build their VC3.1 400mm, or is looking for inspiration for their own project.  This requires you to remove two extrusions in the frame to replace the electronics panel, so likely only something you want to do if you are having significant issues or have not yet built (or are okay with having to re-square your frame after this mod).  The easiest way to replace the electronics panel is to remove just the bottom two extrusions that run front to back.  It's also helpful to have some extra M6 roll in nuts as they make later reassembling these two extrusions.

BOM:

1. Rear Panel - Recommend ACM/ACP or Polycarbonate. 3mm MAX (thicker will hit the rear motors)
   1. 1x VC3.1 400mm Rear Panel
2. Printed Parts:
   1. ABS or ASA:
      1. 1x Cable Guide, Main Top
      2. 1x Cable Guide, Main Bottom
      3. 3x 240mm Cable Guide
      4. 2x DIN Rail Mount 
      5. 4x Octopus Standoffs
      6. 4x Raspberry Pi Standoffs
      7. 24x 40mm Clips + 1x specialized 40mm clip (will be done in the future, not strictly needed***)
      8. 36x 30mm Clips
      9. 1x 120mm Fan Mount
      10. 1x 120mm Fan Duct
      11. 1-2x SSR DIN Rail Clip (1 per SSR)
      12. 1-2x OPTIONAL SSR Spacer for DIN Rail Clip
          1. Helps space out the SSR from the DIN Rail Clip for more cooling
      13. 1x OPTIONAL PSU Power Distribution
          1. Only needed if you want more slots to connect DC voltage devices using Wagos
   2. TPU:
      1. 1x Bed Power Gasket
      2. 2x Filter Fan and Heater Gasket
3. Brackets - Recommend Aluminum
   1. 3mm Thick:
      1. 1x Raspberry Pi + Cable Management Bracket 
      2. 1x Octopus Mount
      3. 1x LRS-150 Mount
      4. 1x Cross Cable Management Bracket
   2. 5mm Thick:
      1. 2x LRS-350 Mount
4. Hardware:
   1. M6:
      1. 20x M6x12mm SHCS
      2. 3x M6x16mm SHCS
      3. 7x M6x18mm Furniture Flat Head Bolt
         1. Example: https://www.amazon.com/dp/B0DRJY1SK5
         2. Not a tapered flat head - need an actually flat flat head that serves as a washer and bolt in one
      4. 30x M6 Spring Loaded 3030 Nuts
         1. Example: https://www.amazon.com/Binzzo-Elastic-Aluminum-Extrusion-Profile/dp/B0841HB5BH
         2. These spring loaded nuts are a better option for the electronics panel than the usually T nuts RatRig uses.  The spring loaded feature means they will stay in place if the bolt is removed, allowing you to change out the PSUs, brackets, or other pieces in the future if they break.  Otherwise the RatRig type T nuts can fall down in the frame when the bolt is removed, meaning nothing will be easily replaceable (and you may have to take the frame partially apart to get a new nut in there). 
   2. M4:
      1. 8x M4x8 FHCS
   3. M3:
      1. 4x M3x35 SHCS
      2. 6x M3x8 SHCS

   4. M2.5:
      1. 4x M2.5x8 SHCS
   5. 6x M3 (4mm OD) Heatset Inserts

      5. 3x block endplates to separate each color of distribution blocks: https://www.digikey.com/en/products/detail/phoenix-contact/3047028/2051200
      6. 2x DIN Rail End Stops (keep the distribution blocks from sliding on the DIN rail): https://www.digikey.com/en/products/detail/altech-corporation/CA702/8547034
      7. Flat Pin Connectors (connect distribution blocks to each other for power distribution). Get the appropriate amount and pin number to connect the number of blocks you need to connect together for each color:
