Reply to Decksavers - Cutting/Drilling/Modding

Has anyone hacked up any of their Decksavers?

I've got one for my DJM850 - but I can't leave the headphones and USB plugged in if I want to use the Decksaver. I don't want to constantly plug and un-plug the USB cable, so I thought of cutting out a hole for the cables to "poke" up through.

Anyone tried this? I thought of drilling and cutting the Decksaver - but I can imagine HUGE cracks developing if I do this!

Anyone actually done it? Or know what material the Decksavers are?
