Ikea Alex Drawer Gridfinity Base

There are a ton of Alex Gridfinity Base options out there, so why this one? Like many of you, I was awfully confused as to which way to go. I had the specs of the bottom of the drawer, I knew there was a small gap to put in the back, but so many options, and several seemed to differ on arrangement, weight of the base, etc.

So, knowing that I needed a 7x12 grid with a spacer, I got into Fusion and made a couple of grids to mate up. I chose 6x4 and 6x3. That means 4 total plates per drawer. Once I had that, I measured for the spacer, took the width of the drawer, cut it in half, and whipped up a spacer block that's split in 2 pieces.

So with the profile I'm adding here, you just run each plate twice and you're set. I didn't find the need for side spacers, like some folks do. Be aware, there are some screws that stick out from the side of the drawer about ⅓ of the way back. You can load it up fully side-to-side, though it will be snug. In the images I've shown here you can see a drawer I've got going as a work in progress as well as one I've completed. Yes, the plate will slide around side-to-side at first. As soon as you've loaded it up with bins that make contact with those screws mentioned here, everything will be quite stable. In other words, the screwheads effectively manage the side gaps.

Personally, I've been printing my drawer bits in eSun's ePLA-Lite. I got a deal on it for about $10/a kilo. If I was going with a Bambu filament, I'd go simple - PLA Basic would do nicely.

Update (1/7/2025): By request, I added an option to print skeletonized bases with magnet holes and connection holes. I don't recommend printing this one, as it eats a LOT more filament and I don't find magnetized bins to be in-demand when used in a desk drawer. On a desk top? For sure, but not inside a drawer. Just my opinion there, but choice is good, so you do you. Those files are in the “STL/CAD files” part of the listing.
