UPDATE to the UPDATE:

First change, I rotated the front ends to better hold a keyboard when you want it out of the way.  Second change is that the connecting rod holes are now static (old model used one of the infill holes which could change location based on print placement).

Still uses 1/8" steel rods, cut to 11" (or whatever you'd like) with a drop of epoxy.  Throw on some rubber feet and you're good to go!

I print mine at 15% honeycomb infill with 3 layers.  No top, no bottom and I use generic PLA.  I'm still rocking an old MK2(s-ish) with a glass plate mode but if you'd like the gcode I use I'd be happy to supply.  (Note:  Position them outside down on the print plate to get a better look on the visible sides)

Apologies for the terrible pics and yes, I probably could get more dust on the keyboard!
