Mario piranha plant pen holder / pot

myminifactory

I wanted something to hold pens but couldn't find the perfect fit, so I decided to create one myself. This pen holder was inspired by Mario's Piranha Plant, but it also serves another purpose - keeping your phone charged with a cable organizer that fits snugly inside. You can even use it to display favorite photos or jot down notes. It's incredibly easy to print and assemble this design. All you'll need is: * A 3D-printed spring with an outer diameter of no more than 8mm and a length of up to 20mm, like this one * A micro-USB cable that suits your needs, such as this one or this alternative option * Some glue for secure bonding Alternatively, you could use an M3x10mm countersunk screw and nut to attach the base instead of relying on adhesive. I'm grateful to Banggood for supporting my design creation.
