Simple cable grommet to cover a 30mm hole in the backer board of an IKEA cabinet (3mm MDF board). The hole was just big enough to fit standard IEC power cable for MK3S.
Printed in PLA, bends enough to get the cable into the grommet before installing the grommet into the hole.
Included Fusion 360 file (.f3d) with history so you can easily change the hole size by editing the first sketch.
The author remixed this model.
