Kệ đựng ly cà phê có khay bí mật

Yeah... I was bored and made an organizer for all my pens crammed into a mug... then I decided to throw in a nested tray that can fit small items like USB drives and sd cards (I usually forget that I've put them there).

The organizer is 83.5mm in diameter, and 76mm tall.  It's a simple design and there should be enough room to resize it as needed in your slicer. The holes for the pens are 15mm in diameter each.
