Rat Rig V-Core 4 High Capacity Electronics Enclosure

Here's a larger electronics enclosure for a VC4 500mm!

This should also fit a VC4 400mm, but will require some changes to the power inlet enclosure bolt hole spacing, the mains conduit piece dimensions, and also drilling holes to mount it on your back panel.  The actual electronics enclosure is too long for a 300mm, but with some tweaking you could likely shave off a few mm and get it to fit if you desire.  STEP file of the entire thing is included to make this easier :)

Features:

1. Up to 3x Meanwell LRS or equivalent PSUs with actual space between PSUs for cooling
2. Dual SSR Mounts (one for bed, one for chamber heater)
3. Larger wire guides for superior cable management
4. Convenient mains power distribution
5. 120mm cooling fans for the Octopus and for the SSRs
6. Option to have independent dual power inlets for 120v countries to enable running powerful chamber heaters if desired.
   1. Circuit 1 in your house and Power Inlet 1 on the printer can be used to power the printer electronics and bed heater as normal.
   2. Circuit 2 and Power Inlet 2 can then be used to power the chamber heater
   3. Ya still need to make sure you have two separate, appropriately rated circuits in your house to use this option though!!!
   4. If using two electrical circuits as described, they need to be wired separately throughout the entire printer (no connecting the circuits electrically inside the printer).
7. Top Mounted Power Switches for easily turning printer on/off

Note: I will be linking some mains voltage items in the BOM.  These are merely the parts I used and they are linked so that you can see what kind of parts you need and the dimensions of those parts.  Before buying any parts for electrical wiring, you need to verify they are appropriate for your specific use case and your country/the electrical grid you will be hooking up to.  Please get an expert's opinion on this if you are unsure. 

BOM:

-Power Inlet & Distribution (linked items are examples only - make sure you get parts that are appropriately rated for the amperage, voltage, and conditions you have calculated that you need!!!):

1. 1-2x C19 Power Inlet(s) (two needed if using two separate circuits): 
   1.  https://www.digikey.com/en/products/detail/schurter-inc/5130-1101/1843959
2.  1-2x Power Switch(es) with built in circuit breaker (two if using two separate circuits):
   1.  https://www.digikey.com/en/products/detail/schurter-inc/4435-0377/2646545
3. DIN Rail Power Distribution Blocks (you need enough to hook up everything you want):
   1. Black: https://www.digikey.com/en/products/detail/phoenix-contact/3045143/2426259
   2. White: https://www.digikey.com/en/products/detail/phoenix-contact/3045130/2426266
   3. Green: https://www.digikey.com/en/products/detail/phoenix-contact/3045156/2426262
   4. DIN Rail Ground Block (optional way to ground DIN Rail): https://www.digikey.com/en/products/detail/phoenix-contact/3044128/2051195
   5. 3x-6x block endplates to separate each color of distribution blocks: https://www.digikey.com/en/products/detail/phoenix-contact/3047028/2051200
      1. 3x if one circuit, 6x if two circuits (one for each color set in each circuit)
   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:
      1. 2 Pin: https://www.digikey.com/en/products/detail/phoenix-contact/3030336/2514720
      2. 3 Pin: https://www.digikey.com/en/products/detail/phoenix-contact/3030242/2525746
      3. 4 Pin: https://www.digikey.com/en/products/detail/phoenix-contact/3030255/2525752
      4. 5 Pin: https://www.digikey.com/en/products/detail/phoenix-contact/3030349/2525762
   8. You need two separate sets of Power Distribution Blocks if using two circuits/power inlets (as the two circuits should be kept separate throughout the printer)
4. ~150mm standard DIN Rail
5. Appropriate gauge wires, crimps, etc

-Hardware (assuming electronics enclosure base plate is between 5.5mm-6mm):

1. 35+ M3x10 FHSC Bolt (Flat head)
2. 40+ M3x8 SHCS Bolt (socket cap head)
3. 80+ M3 Heatset Inserts (4mm OD)
4. 4x M2.5 Heatset inserts (3.5mm OD)
5. 4x M2.5x6 SHCS (will need longer if using WaveShare RPi Hat for IDEX)
6. 12x M4x10 FHSC

8. 6x M4 Nylock Nuts
9. 6x M6x20 SHCS or button head
10. 6x M6 Nylock Nuts

- CNC/Cutting Service & Printed Parts

1. Electronics Enclosure Base Plate
   1. Everything was designed around this plate being 5.6mm (5.5-6mm all work without issue tho).
      1. Can go thicker or thinner, but adjust bolt sizes above accordingly and ensure your plate is thick enough to fully countersink the bolts on the bottom to be flush.  You will need to have a thick enough plate to countersink all the bolt holes though, so don't go too thin.
      2. If changing the thickness of the plate, you will also need to add/remove the same amount from the Mains Conduit.  This was designed to have a thick enough bottom section to be able to take several mm without an issue.
   2. I recommend getting the plate out of Polycarbonate both because it insulates the electronics cabinet from the chamber heat but also because it is easy to countersink the holes to the appropriate size and not have to pay a CNC service to do this ($$$).  Other options that can be countersunk (e.g. aluminum) are acceptable as well.
