MS-01 Bottom Plate Replacement to Support 14mm U.2 NVMe Drive

This print replaces the MS-01 bottom plate so a 14mm NVMEe drive fits.  The existing fan and bracket can be reused.  This uses a modifier mesh to let the slicer make ventilation holes.

Settings at a glance:

• 1 x ms-01 (the main panel): 0.4mm nozzle, 4 walls 40% infill (though lower is probably fine), ABS/PETG
  • mesh-body modifier: 30% rectilinear infill, 0 walls, 0 top/bottom surfaces
• 3 x Spacer: 0.4mm nozzle (though 0.8 will probably work), ABS/PETG
• 4 x Feet: 0.8mm nozzle, 50%+ infill, TPU OR 0.4mm nozzle, PLA/ABS/PETG

Notes/Instructions:

The ms-01-case-extension contains two objects, the ms-01 and the mesh-body, the latter is meant to be used as a modifier.   If using the stl you'll need to “split parts” (the second one is probably the mesh-body). The mesh-body should be converted to a modifier mesh (in orca slicer click “objects” next to "process"), then right click mesh body and then “change type” and select modifier.  Change the mesh-body setting to have 0 wall loops, top shell layers and bottom shell layers; i set the infill to 40% with triangles but 30% with retilinear also works and is less tricky.  I printed the main case with a 0.4 mm nozzle with voron standard settings in black ABS, though my test prints actually had 15% infill and it was fine.  Supports are needed.

The ms-01-case accessories contains two objects, a 7mm spacer that can be printed in whatever (I used ABS but TPU would probably be fine) and a Foot that I printed with TPU with an 0.8mm nozzle, you could print with a non-elastomer and then use adhesive rubber bumpers to prevent sliding. 

Additional hardware:

• 8 x M3x12mm screws (I used BHCS)
• 3 x M2x20mm screws(I used SHCS, there's extra space)

Installation:

1. insert the screws into the fan bracket, add the spacers, then starting with the wifi hole thread them in (this is the least accessible), no need to over-tighten
2. Place the new backplate, be mindful of the cutout for the shroud.  The rear button-clip is pretty close to the edge so you may need to press it a bit.  Align the screw holes by eye.
3. Install the 8 M3 Screws, no need to overtighten.
4. Install the 4 TPU feet, they should press fit 

Caveats:

• With the mod the NVMe is nearly passively cooled sans the slight conduction from the bracket to the fan area, there's space all around the drive, the feet are fairly tall and there's a very wide mesh, seems fine so far with an older Micron 9300 Pro U.2 drive
  • Could add more colling if this was a bit taller, but at that point maybe a new case is in order.
