Hello,

i already have MGN12H rails for this mod.

One Question: The MGN12H Version keeps the original height?

I am trying to get the most of my tornado, so i already modded some parts to get as much x, y and z as possible.

There is some room left between the Y-Carriage and the frame that could be minimized.

One thing though. the 500mm MGN Rail won't fit exactly. The screw holes for the last both might not fit to the extruders front and rear.
To strengthen the rail and to fit, You need a set of Two (2) 2020 20x20mm T-slot V-slot Frame Aluminum Extrusion Cut to 460mm. It will strengthen the rails. I think I got 2 for less than $20.00USD on ebay. Also, These 45°/90° Anchors. Will definitely add strength.

No, The Y-Carriage is raised a few MM. About 3 or 4 mm. Make sure to get Two (2) 2020 20x20mm T-slot V-slot Frame Aluminum Extrusion Cut to 460mm. It will strengthen the rails. I think I got 2 for less than $20.00USD on ebay.

I decided to just attach the SC16UU directly to the Y-Carriage Frame. Using 1/2" Pipe Wall Clamps to secure the 16mm Linear Rod to the Extrusion. This dramatically lowered the Y-Fame. Almost to the point of where it was originally. When I get the Y-Carriage Frame and SC16UU back from the machine shop, I will have Pics/Video. The MGN12H & MGN9C Mount still works great. I am staying with the SC16UU as personal preference.

The Pillow Blocks can be moved more to the center, So that large bed leveling knobs can be used. I'm using ABL and a fixed bed. So, I have my Blocks pretty wide. I will work on this some more.

What material do you suggest printing this in?

I would use PETG, ABS or any such as this. I really wouldn't trust PLA, Especially in an enclosure. I printed my test piece in PLA, and it came out awesome. PLA degrades over time.
