Prometheus hot-end mount for Rostock max and Orion delta printer. E3d version included.

** UPDATE**
Based on suggestions here are a few changes.

• There's now 2 versions of the top plate. One for the Prometheus (4.8mm thick) head and one for the e3d (3.8mm thick)
• J plate zero. This has no standoff built in at all - perfect if you have your own standoffs.
• J plate 4mm. This is the maximum printed standoff you can use with your stock aluminium standoffs and machine screws. It's perfect for using the Prometheus with shorter head configurations (52-58mm)
• J plate 39mm. This switches to a fully printed standoff of 39mm which is perfect for longer Prometheus configs (58-64mm).
• e3d J plate 43mm. Fits the e3d and fan nicely.
• All designed to work with 4mm machine screws.
  UPDATE TRANSMISSION END

This mount is designed to fit onto the Rostock Max V1 & V2. It's a standard J-head mount with hole patterns for the Rostock effector plate.
Since the Prometheus is customizable, just pick the .stl files that are suitable for your needs. 52-58mm for a compact setup and 58-64mm for a longer setup.

I've also included an e3d top plate and a J plate with 43mm printed standoffs which lets the head and fan clear the effector plate.
