Soldering Iron Vertical Stand

This is a simple Soldering Iron Holder. It's for vertical position.
There is a single or a dual holder.
For the dual one, you can use 4 screws or only 2, or adual sided adhesive tape. (the foamy ones).
My soldering iron is 18mm diameter on the thickest part.
I usualy print at 102% size to compensate for thermal shrinking of ABS.
