12mm Middle Plate for RatRig VCore 4.X joiners

If you are using the RatRig machined carriage from the VCore4.1 upgrade kit, you will likely find out that the limit switches have raised up a little bit and the 10mm middle plate on the joiners are a little bit short.

Due that we are offering a replacement for the middle plates that are raised from 10mm to 12mm.  These will be included with the joiners when you buy the whole kit, but this listing is for people who already have them joiners and just need the slightly taller middle plates.
