modable Headset holder

i wanted to make a holder for my headset but thought i would make it customisable.the disc can be made to whatever you like on it and is held on by 8x2 magnets but you should be able to get away with not using them but just there for tolerance purposes. the discs are 40x3mmthere is a small 2mm hole through it to pop the disc out aswell with a bit of filament.i have made 2 versions as i sized it for my desk which is 15.5mm thick and the other is just the top part so you can stick it down with a bit of tape if need be. i can also make another version with it a block at the back and you guys can remove the amount needed
