This is a form fitting, very simple pen holder for the Huion Kamvas 13 drawing tablet/screen.
There is always an unused usb port that now can be utilised as a pen holder. The design is made to be form fitting and hard to fall out and the removal only requires a bit of wiggling. The pen is also a form fit but a bit looser for easy removal so it doesn't scratch the pen surface.
The print in the picture was printed on an original Ender 3 with .2mm layer height and wall count set to 10 just to make sure it doesn't try to use infill and this way the structure is a bit better than with 100% infill. The print time should be around 15 minutes. No supports or skirt needed.
I've also included the .blend file in case someone needs or wants to make modifications. (Check the modifiers.)
