MYNT3D Printing Pen Holder

I use my MYNT3D printing pen to repair or otherwise alter my 3D prints. But I really dislike having to lay the pen down and worry about where the hot tip is touching. So I made this to hold the pen in a vertical position with the tip about an inch off the work surface. Bonus is that the holder actually fits inside the original box that the pen came in so I won't lose it. 
I printed this in PETG but PLA is perfectly fine too, since the hot end doesn't come in contact with the holder.
