New Version!! The place that the tire weights sit has been removed to allow for a lower printing time. (They were not useful anyway)

LEDs There are now holes for LEDs on each of the two slots so that you can have RGB or the search function (just need to add a reed switch to the bottom)

Holes The Holes have been changed so that they are now a inch apart and 1/4" in diameter so that it can be used on a pegboard.

So you want to stack up? but all Zack will give you is stacking on a flat surface because he doesn't want your parts falling out? well fear no more as you can stack Gridfinity along your walls now along with your desk! got a wall with nothing on it? cover it in the Wall Stack-able Gridfinity bases and fill it with all sorts of different bins for all your parts needs! supports up to 6 unit tall blocks with a maximum depth of 1 unit, it can be as long as you want though!

I AM NOT LIABLE FOR YOUR STUFF FALLING ON TO YOUR TABLE

Thanks to Zack Freedman for the Gridfinity system!
