headphone stand with secret storage compartment

If your Asian parent that has no respect of your personal privacy visit your house, you might need a somewhat discrete place to store your 90mm x 190mm cylindrical toy that weight about 400g with its water base operational solution. The best place will be hiding it under plain sight, like who will suspect your headphone stand is empty inside, am I right?

Jokes aside,  I made this headphone stand to hold my extra balance cable as well as connector converters to make it look neat. There are 2 size, and I will recommended the “universal” size to everyone. The “extra large” size is made for people that either has electric static headphone, or want to use it to stretch your headband. 

If you want to make the cover extra secure, you can use some 4mmx2mm neodymium magnet, but I test it without it, and it have not problem to hold its own wait upside-down.
