Desk or Table Basket with Optional Hook

I designed this to hold my ear buds, keys, and an arm band phone pocket. The basket's 70mm tall by 80mm in diameter. Technically could be used as a cup holder if you use a fairly sturdy filament. 

Attaches to desks or tables up to 30mm (1.2") thick. 

All parts print without support. Print the basket, bolt and either one of the clamps (depending on whether you need a hook). If you just need the hook, you can skip printing the basket altogether.

You'll need a couple m3×12 bolts to assemble.
