2U Parametric 10 Inch Server Rack Mount

I apologize for the screenshot! This was made at the request of someone else and it doesn't fit on my printer, so I am not able to provide a build. Please someone post a make so I can have a real image to use for this.

2U version of my parametric 10 inch server rack mount based on FreeCAD spreadsheets. Unfortunately this no longer fits on a Prusa 250x210mm bed so I am not able to test it, but sticking to the recommended print settings of the 1U version it should hold a fair bit of weight.

Recommended print settings:

• 0.2mm layer height
• 4+ bottom layers and 5+ top layers
• 6 perimeters w/ 0.6mm nozzle or 9 perimeters w/ 0.4mm nozzle
• 10+% infill

If you just want to adjust the model to fit your box you only need to tweak the first three parameters. Here's a brief description of the rest:

• rack_thickness: thickness of the rack aside from the front panel.
• rack_gap: margin added to the device width, height, and depth. I've found 0.5mm to be plenty to provide clearance without feeling loose
• offcenter_distance: shifts the mount off center left/right relative to the 1u plate
• hex_side: length of one side of a hexagon cutout
• hex_gap: distance between edges of hexagon cutouts
• hex_outer_gap: distance between outside of mount and beginning of hex cutouts

NOTE: FreeCAD with spreadsheets is awfully slow to update/save/export, at least on my computer. You may need to wait a minute for the model to recalculate after updating each value. Also I did a bit of stability testing on the CAD model but it's still (very) far from indestructible if you start plugging in extreme numbers. If you find an obvious issue let me know and I'll do what I can to fix it!
