Solar Panel Cable Clip for 30x30mm profile

I did not like few solar cable clips that I have tried, so I have designed my own that sits snug, clips over the panel edge, and hides the cable under the solar panel frame. 
It fits perfectly with HYUNDAI HIE-S440HG G12 which has 1.2mm thickness of the flat part of the 30x30mm profile. You can find panel datasheet in the files section if you are interested. 
Panel is mounted to my truck to camper conversion, so all is hidden under the panel including the cable entry grommet and tilting mechanism. It is best to be printed out of ASA. PETG should be fine too as it it almost completely protected from UV radiation, but not from the heat.
