An Ikea trofast storage bin handle. You just click it into place and have a nice handle for the bins.

We use 2 large bins underneath our desk so everything is off the ground and it's easy to clean the floor. The bins are far away under the desk and where not easy to grab, so I made this handle for it. No screws needed just click it under the edge of the bin.

I printed these with 10% infill.
