Laptop desk power cable holder

Summary Made on request of my Mrs. who got tired of diving under the desk to fish out the power cable every time she moves the laptop. Made for 35 mm table top thickness and a 4mm diameter cable. Need support unfortunately, one layer air gap and 0.8 in xy worked fine on mine, clean snap of. Any other orientation and the cable holding bit breaks off. I think its in the wrong orientation by default, sorry about that.
