A pretty small cable organizer that clips onto your desktop. Fits IKEA models like Linnmon, Lagkapten, and Mittcirkel which all have a 3.4cm high desktop. Leaves a tiny bit of wiggle room which you should use to put something thin but grippy in between like a thin rubberized pad, or a small rubber band to ensure it grips in place well. It has a bit of flex so you can easily insert cables both in the front (bigger, 4) and in the backside (more snug, 3, and a bit wider, 2). Can be printed in PLA as well which works fine although you are probably better off with PETG for strength. Needs to be printed with some support but it's not too bad (tree support as in the attached profile seems to work well). You can attach it upside down as well if you prefer that style. Goes well together with this headphone holder: https://makerworld.com/en/models/208678
