This is a remix of my previous remix of ChiMuFeng's laptop stand. I shortened the front tabs because the laptop really only uses the first little bit ...to hold in place, the rest is wasted space and making them shorter allowed for easier insertion/removal. I also dropped some unneeded material by dropping in some empty space. I used (3) 1/8" metal or plastic rods to connect the two sides (fits perfectly in the hex infill) and then some rubber feet for the bottom to keep things from sliding.
I've also included a cut-down version of the stand without any rear support. Only use if your laptop is front-heavy.
