Brackets for Ikea Palycke basket

I bought an Ikea Palycke basket only to find out that it doesn't really fit where I wanted to place it, so I designed these brackets to mount it under a desk.

The tapered holes are made for 5 mm, flat head wood screws. Depending on how deep you can screw them, I think you can use smaller ones too. The Palycke is meant to hold a maximum of 2 Kg anyways, but I am taking no chances.

There is also a hole for an M4x6 heat insert if you want to add a screw and lock in place the thing troug the retaining hole in the palycke brackets, please note that this means that the orientation of the brackets matter, if you mount them front-to-back the hole doesn't allign. 

I made both a “double” version with four holding screws each, and a couple of “one sided” brackets only (one is just the mirror of the other) which I suggest to use with the rails facing outwards  like this → _|  |_ .
