This is a USB holder in the shape of Diablo's skull.
The model is the same as the original, but the .3mf brings a few additions:
I printed it using Spectrum's Wizard Indigo Premium PLA, which gives the model those awesome purple/green reflections. I printed with 15% infill to give it a bit of weight, and a layer height of 0.15mm, but those can be changed.
The author remixed this model.
Added a negative volume so that a USB stick fits nicely in the skull. (I wish I could upload the .3mf on the original model's page, but oh well…)
